本願出願人は、合わせガラスタイプを基本とした採光型の太陽電池パネルによる太陽光発電システムを、「サンジュール（ＳＵＮＪＯＵＬＥ）：登録商標」の商品名で商品化している。合わせガラスタイプとは、２枚のガラス板の間に太陽電池セルを挟み込んだものの他、合わせガラスの背面に、スペーサーを介してもう一枚のガラスを接合した複層ガラスタイプもある。すなわち、従来の太陽電池パネルは、少なくとも２枚のガラス板の間に太陽電池セルを挟み込んで構成されている。   The applicant of the present application has commercialized a solar power generation system based on a daylighting type solar cell panel based on a laminated glass type under the trade name of “SUNJOURE: registered trademark”. The laminated glass type includes a multilayer glass type in which a solar cell is sandwiched between two glass plates and another glass is bonded to the back surface of the laminated glass via a spacer. That is, the conventional solar cell panel is configured by sandwiching solar cells between at least two glass plates.

ところで、このような太陽電池パネルのうち、両面受光可能なものとして、以下の太陽電池パネルが従来から知られている。   By the way, the following solar cell panels are conventionally known as what can receive light on both sides among such solar cell panels.

（１）両面受光型発電セルを、両面から２枚の透明な板状体で挟み込んで封着した太陽電池パネル。   (1) A solar cell panel in which a double-sided light-receiving power generation cell is sandwiched and sealed between two transparent plates from both sides.

特開昭６１−２０３８３６号公報JP-A 61-203836 実用新案登録第３１５４１１５号公報Utility Model Registration No. 3154115

しかしながら、両面受光型発電セルを使用した前記（１）の太陽電池パネルは、両面受光型発電セルの発電効率が、２枚の片面受光型発電セルを用いた太陽電池パネルよりも劣り、また、コスト面でも後者に対して劣るという問題があった。また、２枚の片面受光型発電セルを使用して両面受光可能とした前記（２）の太陽電池パネルは、背中合わせとした片面受光型発電セル同士の電気的絶縁が不十分になる虞があった。更に、２枚の太陽電池モジュールによって両面受光可能とした前記（３）の太陽電池パネルは、２枚の太陽電池モジュールを使用するため、部品点数が多くなり製造コストが増大するという欠点があった。   However, in the solar cell panel of (1) using the double-sided light receiving power generation cell, the power generation efficiency of the double-sided light receiving power generation cell is inferior to that of the solar cell panel using two single-sided light receiving power generation cells. There was also a problem that the cost was inferior to the latter. In addition, the solar cell panel of (2) that can receive light on both sides using two single-sided light-receiving power generation cells may result in insufficient electrical insulation between the single-sided light-receiving power generation cells that are back-to-back. It was. Furthermore, the solar cell panel of (3) that can receive light on both sides with two solar cell modules has the disadvantage that the number of components increases and the manufacturing cost increases because two solar cell modules are used. .

本発明は、このような事情に鑑みてなされたもので、２枚の片面受光型発電セルを使用して発電効率を向上させるとともに、２枚の片面受光型発電セル同士の電気的絶縁の問題を解消でき、かつ部品点数を削減することができる両面受光可能な太陽電池パネルを提供することを目的とする。   The present invention has been made in view of such circumstances, and improves power generation efficiency by using two single-sided light-receiving power generation cells, and also has a problem of electrical insulation between the two single-sided light-receiving power generation cells. It is an object of the present invention to provide a solar cell panel capable of receiving light on both sides, which can eliminate the problem and reduce the number of components.

本発明は、前記目的を達成するために、対向して配置した第１及び第２のガラス板と、前記第１及び第２のガラス板の間に配置されるとともに、各々の非受光面が対向して配置された第１及び第２の片面受光型発電セルと、前記第１及び第２の片面受光型発電セルの各々の非受光面の間に配置された第３のガラス板と、を備えたことを特徴とする太陽電池パネルを提供する。   In order to achieve the above object, the present invention is arranged between the first and second glass plates arranged opposite to each other and the first and second glass plates, and the respective non-light-receiving surfaces face each other. And the first and second single-sided light-receiving power generation cells, and a third glass plate disposed between the non-light-receiving surfaces of the first and second single-sided light-receiving power generation cells. A solar cell panel characterized by the above is provided.

本発明の太陽電池パネルは、第１〜第３のガラス板と第１及び第２の片面受光型発電セルを備え、第１のガラス板と第３のガラス板との間に第１の片面受光型発電セルを配置し、第３のガラス板と第２のガラス板との間に第２の片面受光型発電セルを配置した三重構成の合わせガラス構造を有する両面受光可能な太陽電池パネルである。   The solar cell panel of the present invention includes first to third glass plates and first and second single-side light receiving power generation cells, and the first single side between the first glass plate and the third glass plate. A solar panel capable of receiving light on both sides having a triple-layer laminated glass structure in which a light-receiving power generation cell is disposed and a second single-side light-receiving power generation cell is disposed between a third glass plate and a second glass plate. is there.

したがって、本発明の太陽電池パネルによれば、２枚の片面受光型発電セルを使用したので、発電効率を向上させることができる。   Therefore, according to the solar cell panel of the present invention, the power generation efficiency can be improved because two single-sided light receiving power generation cells are used.

また、本発明の太陽電池パネルでは、第１及び第２の片面受光型発電セルの間に第３のガラス板を介在させたので、第１及び第２の片面受光型発電セル同士の電気的絶縁が確実になされる。   In the solar cell panel of the present invention, since the third glass plate is interposed between the first and second single-side light receiving power generation cells, the electrical connection between the first and second single-side light receiving power generation cells is achieved. Insulation is ensured.

更に、本発明の太陽電池パネルは、１枚の太陽電池モジュールからなる構成なので、２枚の太陽電池モジュールを使用した太陽電池パネルよりも、部品点数を削減でき、製造コストを下げることができる。   Furthermore, since the solar cell panel of the present invention is composed of one solar cell module, the number of parts can be reduced and the manufacturing cost can be reduced as compared with a solar cell panel using two solar cell modules.

本発明において、前記第１のガラス板と前記第１の片面受光型発電セルとの間、該第１の片面受光型発電セルと前記第３のガラス板との間、該第３のガラス板と前記第２の片面受光型発電セルとの間、及び該第２の片面受光型発電セルと前記第２のガラス板との間には、封着用の中間膜がそれぞれ配置されていることが好ましい。   In the present invention, between the first glass plate and the first single-side light receiving power generation cell, between the first single-side light receiving power generation cell and the third glass plate, the third glass plate. And an intermediate film for sealing are respectively disposed between the second single-side light receiving power generation cell and between the second single-side light receiving power generation cell and the second glass plate. preferable.

本発明によれば、４枚の中間膜を太陽電池パネルに備えたので、太陽電池パネルの耐貫通性能が向上する。したがって、本発明の太陽電池パネルは、安全性、防犯性が向上する。   According to the present invention, since the four intermediate films are provided in the solar cell panel, the penetration resistance performance of the solar cell panel is improved. Therefore, the solar cell panel of the present invention improves safety and crime prevention.

本発明において、前記第１及び第２のガラス板は、前記第３のガラス板よりも板厚が薄いことが好ましい。   In the present invention, the first and second glass plates are preferably thinner than the third glass plate.

本発明によれば、外側の第１及び第２のガラス板を、第３のガラス板よりも薄くすることができる。太陽電池パネルに使用されるガラス板は、風圧などに対する強度を確保するために、必要最低限の板厚が必要となる。２枚のガラス板の間に１枚の両面受光型発電セルを配置した太陽電池パネル、及び２枚のガラス板の間に２枚の片面受光型発電セルを背中合わせに配置した太陽電池パネルでは、どうしても受光面のガラス板（カバーガラス）の板厚が厚くなり、セルの発電効率を下げる一因となる。そのため、従来は、高価な高透過ガラスを用いてセルの発電効率を維持していた。   According to the present invention, the outer first and second glass plates can be made thinner than the third glass plate. A glass plate used for a solar cell panel needs a minimum necessary plate thickness in order to ensure strength against wind pressure and the like. In a solar battery panel in which one double-sided light-receiving power generation cell is disposed between two glass plates, and in a solar battery panel in which two single-sided light-receiving power generation cells are disposed back-to-back between two glass plates, the light-receiving surface is unavoidable. The thickness of the glass plate (cover glass) increases, which contributes to lowering the power generation efficiency of the cell. Therefore, conventionally, the power generation efficiency of the cell has been maintained using expensive high-permeability glass.

これに対し、本発明の太陽電池パネルでは、片面受光型発電セルのカバーガラスとなる外側の第１及び第２のガラス板は最低限の厚さとし、風圧に対しては、中央の第３のガラス板の板厚を厚くすることで対応が可能となる。これにより、太陽電池パネルの耐風圧強度を増大させても、片面受光型発電セルの発電効率を維持することができる。また、第１及び第２のガラス板の板厚が薄くて済むので、第１及び第２のガラス板に高透過タイプでない安価な通常のソーダライムガラスなどを使用できる効果も得られる。   On the other hand, in the solar cell panel of the present invention, the first and second glass plates on the outside serving as the cover glass of the single-sided light-receiving power generation cell are set to the minimum thickness, and the third pressure at the center against the wind pressure. This can be achieved by increasing the thickness of the glass plate. Thereby, even if the wind pressure strength of a solar cell panel is increased, the power generation efficiency of the single-sided light-receiving power generation cell can be maintained. Moreover, since the thickness of the first and second glass plates can be thin, an effect of using an inexpensive ordinary soda lime glass which is not a high transmission type for the first and second glass plates can be obtained.

本発明において、前記第１及び第２のガラス板は無着色のガラス板であり、前記第３のガラス板は有着色のガラス板であることが好ましい。   In the present invention, the first and second glass plates are preferably uncolored glass plates, and the third glass plate is preferably a colored glass plate.

本発明によれば、内側の第３のガラス板に色付きガラス（熱線反射、熱線吸収ガラス）を使用した両面受光型の太陽電池パネルを提供することができる。   ADVANTAGE OF THE INVENTION According to this invention, the double-sided light reception type solar cell panel which uses colored glass (heat ray reflection, heat ray absorption glass) for an inner 3rd glass plate can be provided.

これに対し、２枚のガラス板の間に１枚の両面受光型発電セルを配置した太陽電池パネル、及び２枚のガラス板の間に２枚の片面受光型発電セルを背中合わせに配置した太陽電池パネルでは、色付きガラスをカバーガラスに用いると、セルのどちらかの受光面が色付きガラスによって覆われるため、その受光面の発電効率が大きく低下する。本発明においては、内側の第３のガラス板を色付きガラスとすることで、発電効率を低下させることなく、色付きガラスを用いることができる。   On the other hand, in a solar cell panel in which one double-sided light-receiving power generation cell is arranged between two glass plates, and in a solar cell panel in which two single-sided light-receiving power generation cells are arranged back to back between two glass plates, When colored glass is used for the cover glass, since either one of the light receiving surfaces of the cell is covered with the colored glass, the power generation efficiency of the light receiving surface is greatly reduced. In the present invention, colored glass can be used without reducing the power generation efficiency by making the third glass plate on the inner side colored glass.

本発明において、前記第３のガラス板の縁部が、前記第１及び第２のガラス板の縁部に対して外側又は内側に配されたことが好ましい。   In this invention, it is preferable that the edge part of the said 3rd glass plate was distribute | arranged to the outer side or the inner side with respect to the edge part of the said 1st and 2nd glass plate.

本発明の太陽電池パネルによれば、その縁部が段違いの合わせガラスになるため、段違い部分の凹部を、セルの配線スペースとして有効利用することができる。これにより、本発明の太陽電池パネルによれば、配線の納まりが向上するので、外観の見栄えが向上する。   According to the solar cell panel of the present invention, the edge portion becomes a laminated glass having a different level, so that the concave portion of the level difference can be effectively used as a wiring space of the cell. Thereby, according to the solar cell panel of this invention, since the accommodation of wiring improves, the appearance of an external appearance improves.

なお、第１〜第３のガラス板に代えて、アクリルなどの透明樹脂製の板状体を使用してもよい。   In addition, it may replace with the 1st-3rd glass plate and may use the transparent resin-made plate-like bodies, such as an acryl.

本発明の両面受光可能な太陽電池パネルによれば、２枚の片面受光型発電セルを使用したので発電効率を向上させることができ、また、２枚の片面受光型発電セルの間に第３のガラス板を配置したので、２枚の片面受光型発電セル同士の電気的絶縁の問題を解消でき、更に、１枚の太陽電池モジュール構成としたので、部品点数を削減することができる。   According to the solar panel capable of receiving both sides of the present invention, the power generation efficiency can be improved because the two single-sided light-receiving power generation cells are used, and the third one is interposed between the two single-sided light-receiving power generation cells. Since the glass plate is disposed, the problem of electrical insulation between the two single-sided light-receiving power generation cells can be solved, and furthermore, the configuration of one solar cell module can reduce the number of parts.

Since the holeless point support member 15 is well known, the description thereof is omitted here. Further, the lower portion of the solar cell panel 10 is sandwiched between U-shaped brackets 17 and supported by the support columns 14 via the brackets 17.

図２には、太陽電池パネル１０の要部拡大断面図が示されている。   FIG. 2 shows an enlarged cross-sectional view of the main part of the solar cell panel 10.

太陽電池パネル１０は、外側に配置された透明のガラス板（第１のガラス板）１８とガラス板（第２のガラス板）２０、及び内側に配置されたガラス板（第３のガラス板）２２を備える。また、ガラス板１８とガラス板２２との間には、片面受光型発電セル（第１の片面受光型発電セル）２４が配置され、ガラス板２２とガラス板２０との間には、片面受光型発電セル（第２の片面受光型発電セル）２６が配置されている。片面受光型発電セル２４は、受光面をガラス板１８に向けて配置され、片面受光型発電セル２６は、受光面をガラス板２０に向けて配置されている。したがって、実施の形態の太陽電池パネル１０は、三重構成の合わせガラス構造を有する両面受光可能な太陽電池パネルである。   The solar cell panel 10 includes a transparent glass plate (first glass plate) 18 and a glass plate (second glass plate) 20 arranged outside, and a glass plate (third glass plate) arranged inside. 22. A single-sided light-receiving power generation cell (first single-sided light-receiving power generation cell) 24 is disposed between the glass plate 18 and the glass plate 22, and single-sided light reception is provided between the glass plate 22 and the glass plate 20.

The single-sided light-receiving power generation cell 24 is disposed with the light-receiving surface facing the glass plate 18, and the single-sided light-receiving power generation cell 26 is disposed with the light-receiving surface facing the glass plate 20. Therefore, the solar cell panel 10 according to the embodiment is a solar cell panel having a triple-layer laminated glass structure and capable of receiving light on both sides.

片面受光型発電セル２４、２６は、その非受光面がガラス板２２を挟んで背中合わせになるように配置されている。これらの片面受光型発電セル２４、２６は、図１に示すように各々に半田付けされるインターコネクタ３０によって直列に接続されている。   The single-side light-receiving power generation cells 24 and 26 are arranged so that their non-light-receiving surfaces are back to back with the glass plate 22 in between. These single-sided light-receiving cells 24 and 26 are connected in series by an interconnector 30 that is soldered to each other as shown in FIG.

また、図２に示すように、片面受光型発電セル２４の受光面とガラス板１８との間には中間膜３２Ａが介在され、片面受光型発電セル２４の非受光面とガラス板２２との間には中間膜３２Ｂが介在され、ガラス板２２と片面受光型発電セル２６の非受光面との間には中間膜３２Ｃが介在され、片面受光型発電セル２６の受光面とガラス板２０との間には中間膜３２Ｄが介在されている。これらの中間膜３２Ａ〜３２Ｄとしては、合わせガラスの中間膜として用いられるエチレンビニルアセテート製、又はポリビニルブチラール製などのものが使用される。これらの中間膜３２Ａ〜３２Ｄをガラス板１８、２０、２２とともに加熱及び加圧することにより片面受光型発電セル２４、２６がガラス板１８、２０、２２の間に封止されて太陽電池パネル１０が構成される。なお、片面受光型発電セル２４、２６としては、結晶質のものと非晶質のものがあり、どちらでも使用可能である。   Further, as shown in FIG. 2, an intermediate film 32A is interposed between the light receiving surface of the single-sided light-receiving power generation cell 24 and the glass plate 18, and the non-light-receiving surface of the single-sided light-receiving power generation cell 24 and the glass plate 22 are interposed. An intermediate film 32B is interposed therebetween, and an intermediate film 32C is interposed between the glass plate 22 and the non-light-receiving surface of the single-sided light-receiving power generation cell 26, and the light-receiving surface of the single-sided light-receiving power generation cell 26 and the glass plate 20 An intermediate film 32D is interposed between them. As these intermediate films 32A to 32D, those made of ethylene vinyl acetate or polyvinyl butyral used as an intermediate film of laminated glass are used. By heating and pressurizing these intermediate films 32A to 32D together with the glass plates 18, 20, and 22, the single-sided light-receiving power generation cells 24 and 26 are sealed between the glass plates 18, 20, and 22 so that the solar cell panel 10 is formed. Composed. The single-side light-receiving power generation cells 24 and 26 include crystalline ones and amorphous ones, and either one can be used.

次に、前記の如く構成された太陽電池パネル１０の特徴について説明する。   Next, the characteristics of the solar cell panel 10 configured as described above will be described.

前述したように、実施の形態の太陽電池パネル１０は、３枚のガラス板１８、２０、２２と片面受光型発電セル２４、２６を備え、ガラス板１８とガラス板２２との間に片面受光型発電セル２４を配置し、ガラス板２２とガラス板２０との間に片面受光型発電セル２６を配置した三重構成の合わせガラス構造を有する両面受光可能な太陽電池パネルである。   As described above, the solar cell panel 10 according to the embodiment includes the three glass plates 18, 20, 22 and the single-sided light-receiving power generation cells 24, 26, and single-sided light reception between the glass plate 18 and the glass plate 22. It is a solar panel capable of receiving light on both sides, having a triple laminated glass structure in which a power generation cell 24 is disposed and a single-sided light-receiving power cell 26 is disposed between a glass plate 22 and a glass plate 20.

したがって、実施の形態の太陽電池パネル１０によれば、２枚1対の片面受光型発電セル２４、２６を使用したので、両面受光型発電セル1枚分を使用した太陽電池パネルと比較して、発電効率を向上させることができる。また、両面受光型発電セルは、普及タイプの片面受光型発電セル２４、２６に対してコストが高い。条件によっては２枚1対の片面受光型発電セル２４、２６を使用した方が、１枚の両面受光型発電セルを用いるよりも、太陽電池パネル１０全体としてのコストを下げることができる。   Therefore, according to the solar cell panel 10 of the embodiment, since one pair of single-side light receiving power generation cells 24 and 26 is used, compared with a solar cell panel using one double-sided light receiving power generation cell. , Power generation efficiency can be improved. In addition, the double-sided light-receiving power generation cell is more expensive than the popular single-sided light-receiving power cells 24 and 26. Depending on conditions, the cost of the entire solar cell panel 10 can be reduced by using a pair of single-side light-receiving power generation cells 24 and 26 rather than using a single double-sided light-receiving power generation cell.

また、実施の形態の太陽電池パネル１０では、片面受光型発電セル２４と片面受光型発電セル２６同士の電気的絶縁が確実になされる。   Moreover, in the solar cell panel 10 of embodiment, the electrical insulation of the single-sided light-receiving power generation cell 24 and the single-sided light-receiving power generation cell 26 is ensured.

図３の断面図の如く、２枚の片面受光型発電セル１００、１０２を背中合わせにし、その間に樹脂製の中間膜１０４Ａのみを介在させた構成の太陽電池パネル１０６が知られている。この太陽電池パネル１０６は、片面受光型発電セル１００とカバーガラス１０８との間にも中間膜１０４Ｂが介在され、片面受光型発電セル１０２とカバーガラス１１０との間にも中間膜１０４Ｃが介在されている。この太陽電池パネル１０６では、中間膜１０４Ａの溶着時の膜自体の変形、流動により、片面受光型発電セル１００、１０２同士の電気的絶縁が不十分になる虞がある。また、片面受光型発電セル１００、１０２同士の配線接続の際、熱によって中間膜１０４Ａが損傷し、小孔などが空き、電気的絶縁が不十分になる虞がある。   As shown in the cross-sectional view of FIG. 3, there is known a solar cell panel 106 having a configuration in which two single-side light-receiving power generation cells 100 and 102 are back to back, and only a resin intermediate film 104A is interposed therebetween. In this solar cell panel 106, an intermediate film 104B is also interposed between the single-sided light-receiving power generation cell 100 and the cover glass 108, and an intermediate film 104C is also interposed between the single-sided light-receiving power generation cell 102 and the cover glass 110. ing. In this solar cell panel 106, there is a possibility that the electrical insulation between the single-sided light-receiving power generation cells 100 and 102 becomes insufficient due to deformation and flow of the film itself when the intermediate film 104A is welded. Further, when wiring is connected between the single-sided light-receiving power generation cells 100 and 102, the intermediate film 104A may be damaged by heat, and a small hole or the like may be formed, resulting in insufficient electrical insulation.

このような太陽電池パネル１０６に対して、実施の形態の太陽電池パネル１０は、図２の如く、片面受光型発電セル２４、２６の間にガラス板２２が介在されている。よって、中間膜３２Ａ〜３２Ｄの溶着時に中間膜３２Ａ〜３２Ｄが変形、流動したり、片面受光型発電セル２４、２６の配線接続の際に中間膜３２Ａ〜３２Ｄが損傷して小孔が空いたりしても、片面受光型発電セル２４、２６同士はガラス板２２によって電気的に絶縁される。   In contrast to such a solar battery panel 106, the solar battery panel 10 of the embodiment has a glass plate 22 interposed between the single-sided light-receiving power generation cells 24 and 26 as shown in FIG. Therefore, the intermediate films 32A to 32D are deformed and flow when the intermediate films 32A to 32D are welded, or the intermediate films 32A to 32D are damaged when the single-sided light-receiving power generation cells 24 and 26 are connected to form small holes. Even so, the single-sided light-receiving power generation cells 24 and 26 are electrically insulated by the glass plate 22.

更に、実施の形態の太陽電池パネル１０は、１枚の太陽電池モジュールからなる構成なので、２枚の太陽電池モジュールを使用した２重モジュール構成の太陽電池パネルよりも、部品点数を削減でき、製造コストを下げることができる。すなわち、２重モジュール構成の太陽電池パネルは、１枚の太陽電池モジュールにつき２枚のカバーガラスを必要とするため、合計で４枚のカバーガラスが必要となり、かつ、双方の太陽電池モジュールを仕切る仕切り部材が必要になる。よって、３枚のガラス板１８、２０、２２からなる実施の形態の太陽電池パネル１０と比較して、部品点数が多くなり、製造コストも嵩む。   Furthermore, since the solar cell panel 10 according to the embodiment is composed of a single solar cell module, the number of components can be reduced compared with a solar cell panel having a dual module configuration using two solar cell modules. Cost can be reduced. That is, since a solar cell panel having a double module configuration requires two cover glasses for each solar cell module, a total of four cover glasses are required, and both solar cell modules are partitioned. A partition member is required. Therefore, compared with the solar cell panel 10 of embodiment which consists of the three glass plates 18, 20, and 22, a number of parts increases and manufacturing cost also increases.

更にまた、実施の形態の太陽電池パネル１０では、片面受光型発電セル２４、２６の優位性を生かすことができる。現時点で、片面受光型発電セル２４、２６の発電効率は、両面受光型発電セルの発電効率よりも優れている。２枚の片面受光型発電セル２４、２６を太陽電池パネル１０に用いることで、１枚の両面受光型発電セルを用いた太陽電池パネルよりも発電効率の高い太陽電池パネル１０とすることができる。   Furthermore, in the solar cell panel 10 of the embodiment, the superiority of the single-sided light-receiving power generation cells 24 and 26 can be utilized. At present, the power generation efficiency of the single-sided light-receiving power generation cells 24 and 26 is superior to that of the double-sided light-receiving power generation cells. By using the two single-sided light-receiving power generation cells 24 and 26 in the solar battery panel 10, the solar battery panel 10 having higher power generation efficiency than the solar battery panel using one double-sided light-receiving power generation cell can be obtained. .

また、実施の形態の太陽電池パネル１０では、片面受光型発電セル２４と片面受光型発電セル２６の系統を別々にすることができるので、配線が容易になるという利点がある。   Moreover, in the solar cell panel 10 of embodiment, since the system | strain of the single-sided light reception type power generation cell 24 and the single-sided light reception type power generation cell 26 can be made separate, there exists an advantage that wiring becomes easy.

更に、実施の形態の太陽電池パネル１０では、片面受光型発電セル２４と片面受光型発電セル２６の配置位置を変えることができる。これにより、双方の片面受光型発電セル２４、２６の配置をずらすことで、太陽電池パネル１０の発電セル同士の間を透過する光の量を調整することができる。また、双方の片面受光型発電セル２４、２６を千鳥格子状（市松模様）に配置するなど、意匠的な自由度も増えるという利点がある。   Furthermore, in the solar cell panel 10 of the embodiment, the arrangement positions of the single-sided light-receiving power generation cell 24 and the single-sided light-receiving power generation cell 26 can be changed. Thereby, the quantity of the light which permeate | transmits between the power generation cells of the solar cell panel 10 can be adjusted by shifting arrangement | positioning of both the single-sided light reception type power generation cells 24 and 26. FIG. Further, there is an advantage that the degree of design freedom is increased, such as arranging both the single-sided light-receiving power generation cells 24 and 26 in a staggered pattern (checkered pattern).

また、一方で実施の形態の太陽電池パネル１０は、４枚の中間膜３２Ａ〜３２Ｄを備えているので、太陽電池パネル１０の耐貫通性能が向上する。   On the other hand, since the solar cell panel 10 of the embodiment includes the four intermediate films 32A to 32D, the penetration resistance of the solar cell panel 10 is improved.

すなわち、図３に示した２枚の片面受光型発電セル１００、１０２の間に中間膜１０４Ａのみを介在させた構成の太陽電池パネル１０６と比較して、実施の形態の太陽電池パネル１０は、中間膜３２Ａ〜３２Ｄの枚数が３枚から４枚に増えるため、耐貫通性能が向上する。したがって、実施の形態の太陽電池パネル１０は、図３に示した太陽電池パネル１０６と比較して安全性、防犯性が向上する。   That is, compared with the solar cell panel 106 having a configuration in which only the intermediate film 104A is interposed between the two single-sided light-receiving power generation cells 100 and 102 shown in FIG. Since the number of the intermediate films 32A to 32D increases from three to four, the penetration resistance is improved. Therefore, the solar cell panel 10 of the embodiment is improved in safety and crime prevention as compared with the solar cell panel 106 shown in FIG.

また、実施の形態の太陽電池パネル１０によれば、中間膜として乳白フィルムなどの着色膜を使用した、意匠性の高い両面受光型の太陽電池パネルを提供することもできる。この着色膜は、双方の片面受光型発電セル２４、２６の発電効率を維持するために、片面受光型発電セル２４の非受光面とガラス板２２との間に配置される中間膜３２Ｂ、及び／又はガラス板２２と片面受光型発電セル２６の非受光面との間に配置される中間膜３２Ｃに適用される。   Moreover, according to the solar cell panel 10 of the embodiment, a double-sided light-receiving solar cell panel having a high design property using a colored film such as a milky white film as an intermediate film can be provided. This colored film includes an intermediate film 32B disposed between the non-light-receiving surface of the single-side light-receiving power generation cell 24 and the glass plate 22 in order to maintain the power generation efficiency of both single-side light-receiving power generation cells 24 and 26, and This is applied to the intermediate film 32 </ b> C disposed between the glass plate 22 and the non-light-receiving surface of the single-sided light-receiving power generation cell 26.

図４には、２枚のガラス板１２０、１２２の間に両面受光型発電セル１２４が封着された太陽電池パネル１２６の断面図が示されている。この太陽電池パネル１２６では、ガラス板１２０と両面受光型発電セル１２４の一方の受光面１２４Ａとの間に中間膜１２８Ａが介在され、ガラス板１２２と両面受光型発電セル１２４の他方の受光面１２４Ｂとの間に中間膜１２８Ｂが介在されている。この場合、２枚の中間膜１２８Ａ、１２８Ｂのうち一枚の中間膜に着色膜を使用すると、両面受光型発電セル１２４の一方の受光面１２４Ａ又は他方の受光面１２４Ｂが着色膜によって覆われるため、その受光面の発電効率が大きく低下するという欠点がある。   FIG. 4 shows a cross-sectional view of a solar battery panel 126 in which a double-sided light-receiving power generation cell 124 is sealed between two glass plates 120 and 122. In this solar cell panel 126, an intermediate film 128A is interposed between the glass plate 120 and one light receiving surface 124A of the double-sided light-receiving power generation cell 124, and the other light receiving surface 124B of the glass plate 122 and the double-sided light-receiving power generation cell 124. An intermediate film 128B is interposed therebetween. In this case, if a colored film is used for one of the two intermediate films 128A and 128B, one light-receiving surface 124A or the other light-receiving surface 124B of the double-sided light-receiving power generation cell 124 is covered with the colored film. There is a drawback that the power generation efficiency of the light receiving surface is greatly reduced.

これに対して、図２に示した実施の形態の太陽電池パネル１０では、片面受光型発電セル２４の非受光面とガラス板２２との間に配置される中間膜３２Ｂ、及び／又はガラス板２２と片面受光型発電セル２６の非受光面との間に配置される中間膜３２Ｃを着色膜としたので、図４の太陽電池パネル１２６が持つ発電効率低下の問題を解消することができる。   On the other hand, in the solar cell panel 10 of the embodiment shown in FIG. 2, the intermediate film 32 </ b> B disposed between the non-light-receiving surface of the single-side light-receiving power generation cell 24 and the glass plate 22 and / or the glass plate. Since the intermediate film 32C disposed between the non-light-receiving surface of the single-sided light-receiving power generation cell 26 is a colored film, the problem of the reduction in power generation efficiency of the solar battery panel 126 of FIG. 4 can be solved.

また、実施の形態の太陽電池パネル１０では、図２の如くカバーガラスであるガラス板１８、２０の板厚を、ガラス板２２の板厚よりも薄くすることができる。   In the solar cell panel 10 of the embodiment, the plate thickness of the glass plates 18 and 20 that are cover glasses can be made thinner than the plate thickness of the glass plate 22 as shown in FIG.

一般に、太陽電池パネルに使用されるガラス板は、風圧などに対する強度を確保するために、必要最低限の板厚が必要となる。図３の如く２枚のガラス板１０８、１１２の間に２枚の片面受光型発電セル１００、１０２を封着した太陽電池パネル１０６、及び図４の如く２枚のガラス板１２０、１２２の間に１枚の両面受光型発電セル１２４を封着した太陽電池パネル１２６では、受光面のカバーガラスであるガラス板１０８、１１２、１２０、１２２の板厚がどうしても厚くなり、セル１００、１０２、１２４の発電効率を下げる一因となる。そのため、図３、図４に示した太陽電池パネル１０６、１２６では、ガラス板１０８、１１０、１２０、１２２に高価な高透過ガラスを使用し、セルの発電効率を維持する必要があった。   In general, a glass plate used for a solar cell panel requires a minimum necessary plate thickness in order to ensure strength against wind pressure and the like. As shown in FIG. 3, between the two glass plates 108 and 112, the solar panel 106 in which the two single-sided light-receiving cells 100 and 102 are sealed, and between the two glass plates 120 and 122 as shown in FIG. In the solar cell panel 126 in which one double-sided light-receiving power generation cell 124 is sealed, the glass plates 108, 112, 120, and 122 that are the cover glass on the light-receiving surface are inevitably thickened. It contributes to lowering the power generation efficiency. Therefore, in the solar cell panels 106 and 126 shown in FIGS. 3 and 4, it is necessary to use expensive high-permeability glass for the glass plates 108, 110, 120, and 122 to maintain the power generation efficiency of the cells.

これに対して、図２に示した実施の形態の太陽電池パネル１０では、片面受光型発電セル２４、２６のカバーガラスとなる外側のガラス板１８、２０を、耐風圧強度を考慮しない最低限の厚さとし、風圧に対しては、中央のガラス板２２の板厚を厚くする。これにより、太陽電池パネル１０全体としての耐風圧強度を確保することができる。   On the other hand, in the solar cell panel 10 of the embodiment shown in FIG. 2, the outer glass plates 18 and 20 serving as cover glasses for the single-sided light-receiving power generation cells 24 and 26 are at least not considered wind resistance strength. For the wind pressure, the thickness of the central glass plate 22 is increased. Thereby, the wind-resistant pressure strength as the solar cell panel 10 whole can be ensured.

したがって、実施の形態の太陽電池パネル１０では、ガラス板２２の板厚を十分に厚くして太陽電池パネル１０の耐風圧強度を増大させても、片面受光型発電セル２４、２６の発電効率を維持することができる。また、ガラス板１８、２０の板厚を薄くすることができるので、ガラス板１８、２０に高透過タイプでない安価な通常のソーダライムガラスなどを使用できる効果も得られる。ここで、通常のソーダライムガラス、高透過ガラスとは、５ｍｍ厚さの透過率で比較した場合、７０％以上の透過率を持つものが通常のソーダライムガラスとし、ガラスの組成中の着色成分を減らし８５％以上の透過率を持つものを高透過ガラスと呼んでいる。   Therefore, in the solar cell panel 10 of the embodiment, even if the plate thickness of the glass plate 22 is sufficiently increased to increase the wind pressure strength of the solar cell panel 10, the power generation efficiency of the single-sided light receiving power generation cells 24, 26 is improved. Can be maintained. Moreover, since the plate | board thickness of the glass plates 18 and 20 can be made thin, the effect which can use the cheap normal soda-lime glass etc. which are not highly transmissive types for the glass plates 18 and 20 is also acquired. Here, normal soda lime glass and high transmittance glass are those having a transmittance of 70% or more when compared with a transmittance of 5 mm thickness, and a normal soda lime glass is a coloring component in the composition of the glass. A glass with a transmittance of 85% or more is called high transmittance glass.

なお、ガラス板２２は、光透過機能を備える必要がないので、板厚の厚いソーダライムガラスを用いることが好ましく、又は不透明のガラス板、透明、不透明の樹脂板を用いてもよい。また、ガラス板１８、２０の代わりに、透明の樹脂板を用いてもよい。樹脂板を使用する場合には、中間膜３２Ａ〜３２Ｄの加熱温度に耐え得る材質のものを選定すればよい。   Since the glass plate 22 does not need to have a light transmission function, it is preferable to use a thick soda lime glass, or an opaque glass plate, a transparent or opaque resin plate may be used. Further, instead of the glass plates 18 and 20, a transparent resin plate may be used. When a resin plate is used, a material that can withstand the heating temperature of the intermediate films 32A to 32D may be selected.

一方、実施の形態の太陽電池パネル１０では、外側のガラス板１８、２０を無着色のガラス板とし、中央のガラス板２２を有着色のガラス板とすることができる。すなわち、片面受光型発電セル２４、２６の光受光量に影響を与えない中央のガラス板２２として、熱線反射ガラス、及び熱線吸収ガラスなどの機能的な色付きガラスを使用することができる。   On the other hand, in the solar cell panel 10 of the embodiment, the outer glass plates 18 and 20 can be uncolored glass plates, and the central glass plate 22 can be a colored glass plate. That is, functional colored glass such as heat ray reflecting glass and heat ray absorbing glass can be used as the central glass plate 22 that does not affect the amount of light received by the single-sided light receiving cells 24 and 26.

これに対し、図３の如く２枚のガラス板１０８、１１０の間に２枚の片面受光型発電セル１００、１０２を背中合わせに配置した太陽電池パネル１０６、及び図４の如く２枚のガラス板１２０、１２２の間に１枚の両面受光型発電セル１２４を配置した太陽電池パネル１２６では、色付きガラスをカバーガラスに用いると、セル１００、１０２、１２４のどちらかの受光面が色付きガラスによって覆われるため、その受光面の発電効率が大きく低下する。   On the other hand, a solar cell panel 106 in which two single-sided light-receiving power generation cells 100 and 102 are arranged back-to-back between two glass plates 108 and 110 as shown in FIG. 3, and two glass plates as shown in FIG. In the solar battery panel 126 in which one double-sided light-receiving power generation cell 124 is disposed between 120 and 122, when colored glass is used as a cover glass, one of the light-receiving surfaces of the cells 100, 102, and 124 is covered with colored glass. Therefore, the power generation efficiency of the light receiving surface is greatly reduced.

実施の形態の太陽電池パネル１０では、中央のガラス板２２を色付きガラスとすることで、発電効率を低下させることなく、色付きガラスを用いることができる。   In the solar cell panel 10 of the embodiment, colored glass can be used without reducing the power generation efficiency by using the central glass plate 22 as colored glass.

図５には、他の実施の形態の太陽電池パネル１０Ａの要部拡大断面図が示されている。この太陽電池パネル１０Ａによれば、中央のガラス板２２の縁部２２Ａに対して外側のガラス板１８、２０の縁部１８Ａ、２０Ａが、外方に同量突出されている。   The principal part expanded sectional view of 10 A of solar cell panels of other embodiment is shown by FIG. According to this solar cell panel 10 </ b> A, the edge portions 18 </ b> A and 20 </ b> A of the outer glass plates 18 and 20 protrude outwardly by the same amount with respect to the edge portion 22 </ b> A of the central glass plate 22.

また、図６には、別の実施の形態の太陽電池パネル１０Ｂの要部拡大断面図が示されている。この太陽電池パネル１０Ｂによれば、外側のガラス板１８、２０の縁部１８Ａ、２０Ａに対して中央のガラス板２２の縁部２２Ａが、外方に突出されている。   Moreover, the principal part expanded sectional view of the solar cell panel 10B of another embodiment is shown by FIG. According to this solar cell panel 10B, the edge 22A of the central glass plate 22 protrudes outward with respect to the edges 18A and 20A of the outer glass plates 18 and 20.

すなわち、図５、図６には、ガラス板２２の縁部Ａが、ガラス板１８、２０の縁部１８Ａ、２０Ａに対して内側、または外側に配された太陽電池パネル１０Ａ、１０Ｂが示されている。なお、図５、図６に示した太陽電池パネル１０Ａ、１０Ｂでは、図２に示した太陽電池パネル１０と同一又は類似の部材について同一の符号を付している。   That is, FIGS. 5 and 6 show solar cell panels 10A and 10B in which the edge A of the glass plate 22 is arranged on the inner side or the outer side with respect to the edge portions 18A and 20A of the glass plates 18 and 20, respectively. ing. In addition, in solar cell panel 10A, 10B shown in FIG. 5, FIG. 6, the same code | symbol is attached | subjected about the same or similar member as the solar cell panel 10 shown in FIG.

図５、図６に示した太陽電池パネル１０Ａ、１０Ｂによれば、ガラス板１８、２０、２２の縁部１８Ａ、２０Ａ、２２Ａが段違いの合わせガラスになる。   According to the solar cell panels 10A and 10B shown in FIGS. 5 and 6, the edge portions 18A, 20A, and 22A of the glass plates 18, 20, and 22 become the laminated glass having different levels.

図５の太陽電池パネル１０Ａにおいては、段違い部分の凹部３４を、すなわち、ガラス板２２の縁部２２Ａと、この縁部２２Ａから突出したガラス板１８、２０のそれぞれの内面１８Ｂ、２０Ｂとで画成される二点鎖線で示した凹部３４を、セルの配線スペースとして有効利用することができる。したがって、図５の太陽電池パネル１０Ａによれば、凹部３４内にセルの配線が収納されるため、配線の納まりが向上する。また、前記配線は、太陽電池パネル１０Ａを外側から見ると、凹部３４内に隠れて見え難いので、図１に示したガラスフェンス１２の外観の見栄えが向上する。   In the solar cell panel 10A of FIG. 5, the recessed portion 34 of the uneven portion is defined by the edge portion 22A of the glass plate 22 and the inner surfaces 18B and 20B of the glass plates 18 and 20 protruding from the edge portion 22A. The recessed part 34 shown with the dashed-two dotted line formed can be used effectively as a wiring space of a cell. Therefore, according to the solar cell panel 10A of FIG. 5, since the wiring of the cell is accommodated in the recess 34, the accommodation of the wiring is improved. Moreover, since the said wiring is difficult to see because it hides in the recessed part 34 when the solar cell panel 10A is seen from the outside, the appearance of the glass fence 12 shown in FIG. 1 is improved.

また、図６の太陽電池パネル１０Ｂにおいては、段違いの凹部３６Ａ、３６Ｂを、すなわち、ガラス板１８、２０の縁部１８Ａ、２０Ａから突出したガラス板２２の両側に画成される二点鎖線で示した凹部３６Ａ、３６Ｂを、セルの配線スペースとして有効利用することができる。したがって、図６の太陽電池パネル１０Ｂによれば、凹部３６Ａ、３６Ｂ内にセルの配線が収納されるため、配線の納まりが向上する。また、配線は、ガラス板１８、２０の表面に対して内側に配線され、ガラス板１８、２０の表面から外側に出ないので、図１に示したガラスフェンス１２の外観の見栄えが向上する。   Moreover, in the solar cell panel 10B of FIG. 6, the recessed parts 36A and 36B of different levels are shown by two-dot chain lines defined on both sides of the glass plate 22 protruding from the edge portions 18A and 20A of the glass plates 18 and 20. The illustrated recesses 36A and 36B can be effectively used as a cell wiring space. Therefore, according to the solar cell panel 10B of FIG. 6, since the wiring of the cell is accommodated in the recesses 36A and 36B, the accommodation of the wiring is improved. Moreover, since wiring is wired inside with respect to the surface of the glass plates 18 and 20, and does not come out from the surface of the glass plates 18 and 20, the appearance of the external appearance of the glass fence 12 shown in FIG. 1 improves.

なお、凹部３４，３６Ａ，３６Ｂは、太陽電池パネル１０Ａ、１０Ｂの全周に渡って設けなくてもよく、配線が必要な部分に凹部を設けてもよい。また、図１のブラケット１７の取付部分に凹部を設置し、見栄えをよくしてもよい。   Note that the recesses 34, 36A, and 36B may not be provided over the entire circumference of the solar cell panels 10A and 10B, and may be provided in portions where wiring is required.
