Description
本発明は、太陽電池と、その受光面の上に設けられたタッチパネルと、を備えた複合入力装置に関する。 The present invention relates to a composite input device including a solar cell and a touch panel provided on a light receiving surface thereof.
太陽電池部材は、光電変換効率の向上が重要な課題であり、そのために光電変換層の膜厚を厚くする、凹凸表面構造からなる”テクスチャ構造”と呼ばれる構造を設け、光をこの”テクスチャ構造”によって光を散乱させることによって、光電変換層を通過する光の光路長を長くして、光電変換層において吸収される光の量を増加させる方法が用いられている。 For solar cell members, improvement of photoelectric conversion efficiency is an important issue. For this purpose, a structure called “texture structure” consisting of an uneven surface structure is provided to increase the film thickness of the photoelectric conversion layer. The method of increasing the amount of light absorbed in the photoelectric conversion layer by increasing the optical path length of the light passing through the photoelectric conversion layer by scattering the light by "" is used.
しかし、テクスチャ構造上に光電変換層（半導体層）を形成した場合、光電変換層に多くの欠陥を誘起し、変換効率を悪化させる場合があることや、光電変換層の膜厚を厚くすることによる材料コストのアップや生産速度の低下などの問題がある。太陽電池において、変換効率向上及び入射角度依存性の解消のために、入射光を散乱光に変換する提案がある（例えば、特許文献１及び２参照。）。 However, when a photoelectric conversion layer (semiconductor layer) is formed on the texture structure, many defects may be induced in the photoelectric conversion layer to deteriorate the conversion efficiency, or the film thickness of the photoelectric conversion layer is increased. There are problems such as an increase in material cost and a decrease in production speed. In solar cells, there is a proposal to convert incident light into scattered light in order to improve conversion efficiency and eliminate incident angle dependency (see, for example, Patent Documents 1 and 2).
一方、太陽電池と透明タッチパネルとを組み合わせたデバイス技術についていくつか提案がなされている（例えば、特許文献３〜６参照。）。このように太陽電池とタッチパネルを組み合わせたデバイスによれば、例えばリモコンとして用いた場合、１次電池を必要としないというメリットがある。 On the other hand, some proposals have been made on device technology combining a solar cell and a transparent touch panel (see, for example, Patent Documents 3 to 6). Thus, according to the device which combined the solar cell and the touch panel, for example, when used as a remote controller, there is an advantage that a primary battery is not required.
しかし、図８の従来のタッチパネルの平面図に示すように、タッチパネルには引き回し配線部２２が存在する。この引き回し配線部２２には銀ペーストなどが用いられる。そのため、図９に示すように、太陽電池１の上に従来のタッチパネル２を配置した場合、引き回し配線部２２の光透過率は低く、有効な受光面として機能しない。その結果、引き回し配線部２２の面積については十分な発電効率が得られないという問題があった。 However, as shown in the plan view of the conventional touch panel in FIG. 8, the lead wiring portion 22 exists in the touch panel. A silver paste or the like is used for the routing wiring portion 22. Therefore, as shown in FIG. 9, when the conventional touch panel 2 is disposed on the solar cell 1, the light transmittance of the routing wiring portion 22 is low and does not function as an effective light receiving surface. As a result, there is a problem that sufficient power generation efficiency cannot be obtained for the area of the routing wiring portion 22.
一方、タッチパネルの透明導電膜として通常使用されているＩＴＯ材料は折り曲げに弱く、わずかな折り曲げであっても抵抗値変化が大きくなる。そのため、引き回し配線部２２を側面に配置することは困難であるという問題があった。 On the other hand, the ITO material normally used as the transparent conductive film of the touch panel is vulnerable to bending, and the resistance value changes greatly even with slight bending. Therefore, there is a problem that it is difficult to arrange the routing wiring portion 22 on the side surface.
そこで、本発明の目的は、太陽電池の上にタッチパネルを設けた複合入力装置において、引き回し配線部による光透過率の低下を防いで、太陽電池に届く光を十分に確保し、太陽電池における光電変換効率を向上させると共に、タッチパネルとしての機能を有する複合入力装置を提供することである。 Accordingly, an object of the present invention is to prevent a decrease in light transmittance due to the routing wiring portion in a composite input device provided with a touch panel on a solar cell, to ensure sufficient light reaching the solar cell, and An object of the present invention is to provide a composite input device that improves conversion efficiency and has a function as a touch panel.

本発明に係る複合入力装置は、太陽電池部の側面にタッチパネル部の透明導電膜と折り曲げ部を介して電気的に接続された引き回し配線部を備える。この折り曲げ部は、導電性ナノワイヤ材料によって構成されており、これによって、タッチパネル部の引き回し配線部を太陽電池部の受光面の上ではなく、太陽電池部の側面に設けることができる。そのため、太陽電池部の受光面を最大限に生かすことができ、発電効率を向上させることができる。 The composite input device according to the present invention includes a lead wiring portion electrically connected to the side surface of the solar cell portion via a transparent conductive film of the touch panel portion and a bent portion. The bent portion is made of a conductive nanowire material, whereby the lead wiring portion of the touch panel portion can be provided not on the light receiving surface of the solar cell portion but on the side surface of the solar cell portion. Therefore, the light receiving surface of the solar cell unit can be utilized to the maximum, and the power generation efficiency can be improved.

(Embodiment 1)
FIG. 1 is a schematic cross-sectional view showing a cross-sectional structure of the composite input device 10 according to the first embodiment. FIG. 2 is a partial cross-sectional view showing a cross-sectional structure of a connection portion between the lead wiring portion 22 at the end portion of FIG. 1 and the transparent conductive film 4 of the touch panel portion 2. FIG. 5 is a conceptual diagram in which the routing wiring portion 22 connected to the transparent conductive film 4 of the touch panel portion 2 of the composite input device 10 is bent along the folding line 23 and arranged on the side surface of the solar cell portion 1. FIG. 6 is a perspective view showing the routing wiring portion 22 of the composite input device 10. FIG. 7A is a schematic cross-sectional view showing a process of bending the lead wiring portion 22 of FIG. 5 along the fold line 23 and arranging it on the side surface of the solar cell portion 1. FIG. 1 is a schematic cross-sectional view showing a cross-sectional structure of a composite input device 10 obtained.
この複合入力装置１０は、太陽電池部１と、太陽電池部１の受光面１２の上に設けられたタッチパネル部２とを備える。また、この複合入力装置１０は、太陽電池部１の側面にタッチパネル部２の透明導電膜４と折り曲げ部２４を介して電気的に接続された引き回し配線部２２を備える。この折り曲げ部２４は、導電性ナノワイヤ材料３によって構成されていることを特徴とする。これによって、タッチパネル部２の引き回し配線部２２を太陽電池部１の受光面１２の上ではなく、太陽電池部１の側面に設けることができる。そのため、太陽電池部１の受光面１２を最大限に生かすことができ、発電効率を向上させることができる。 The composite input device 10 includes a solar cell unit 1 and a touch panel unit 2 provided on a light receiving surface 12 of the solar cell unit 1. The composite input device 10 further includes a lead wiring portion 22 electrically connected to the side surface of the solar cell portion 1 through the transparent conductive film 4 of the touch panel portion 2 and the bent portion 24. The bent portion 24 is configured by the conductive nanowire material 3. Thereby, the routing wiring part 22 of the touch panel part 2 can be provided not on the light receiving surface 12 of the solar cell part 1 but on the side surface of the solar cell part 1. Therefore, the light receiving surface 12 of the solar cell unit 1 can be utilized to the maximum, and the power generation efficiency can be improved.
上記のタッチパネル部２の透明導電膜４と電気的に接続された引き回し配線部２２を太陽電池部１の側面に配置することについてさらに説明する。
図４は、ＩＴＯからなる透明導電膜（◆）と、銀ナノワイヤからなる透明導電膜（■）とについて、８ｍｍφマンドレル屈曲試験テスト結果の折り曲げ回数と抵抗値変化率との関係を示すグラフである。この図４に示すように、通常よく使用されるＩＴＯ（インジウムスズ酸化物）材料からなる透明導電膜は、折り曲げに弱く、わずかな折り曲げであってもその抵抗値が大きく変化する。そのため、図８の従来のタッチパネルの平面図に示すように、透明導電膜４からの引き回し配線部２２は透明導電膜４と同一平面内に設けられていた。この引き回し配線部２２には、通常、銀ペーストが用いられている。図９は、図８のタッチパネル部２を太陽電池部１の上に設けた場合の断面構造を示す断面図である。図９に示すように、従来のタッチパネル２をそのまま太陽電池１の上に設けた場合、銀ペーストによる引き回し配線部２２の部分の光透過率は低く、発電に寄与しない。そのため、引き回し配線部２２を除く部分だけが有効な受光面１２となっていた。
The arrangement of the lead wiring portion 22 electrically connected to the transparent conductive film 4 of the touch panel portion 2 on the side surface of the solar cell portion 1 will be further described.
FIG. 4 is a graph showing the relationship between the number of bendings and the resistance value change rate of the 8 mmφ mandrel bending test results for the transparent conductive film (♦) made of ITO and the transparent conductive film (■) made of silver nanowires. . As shown in FIG. 4, a commonly used transparent conductive film made of ITO (indium tin oxide) material is vulnerable to bending, and its resistance value changes greatly even with slight bending. Therefore, as shown in the plan view of the conventional touch panel in FIG. 8, the lead wiring portion 22 from the transparent conductive film 4 is provided in the same plane as the transparent conductive film 4. A silver paste is usually used for the routing wiring portion 22. FIG. 9 is a cross-sectional view showing a cross-sectional structure when the touch panel unit 2 of FIG. 8 is provided on the solar cell unit 1. As shown in FIG. 9, when the conventional touch panel 2 is provided on the solar cell 1 as it is, the light transmittance of the portion of the lead wiring portion 22 made of silver paste is low and does not contribute to power generation. Therefore, only the portion excluding the routing wiring portion 22 is an effective light receiving surface 12.
この複合入力装置１０では、タッチパネル部２の透明導電膜４と引き回し配線部２２とを電気的に接続する折り曲げ部２４を導電性ナノワイヤ材料３によって構成している。図４の８ｍｍφマンドレル屈曲試験テスト結果に示すように、この導電性ナノワイヤ材料３の一つである銀ナノワイヤ材料からなる透明導電膜は、１０回を越える折り曲げ回数を経ても抵抗値変化がほとんどないほど十分な折り曲げ耐性を有している。そこで、図５及び図７（ａ）に示すように、引き回し配線部２２を折り曲げ線２３で折り曲げた場合でも導電性ナノワイヤ材料３で構成された折り曲げ部２４の抵抗値は変化しない。その結果、図６及び図７（ｂ）に示すように太陽電池部１の側面に引き回し配線部２２を配置でき、太陽電池部１の受光面１２を発電に有効に利用することができる。 In the composite input device 10, the bent portion 24 that electrically connects the transparent conductive film 4 of the touch panel portion 2 and the routing wiring portion 22 is formed of the conductive nanowire material 3. As shown in the 8 mmφ mandrel bending test test result in FIG. 4, the transparent conductive film made of the silver nanowire material, which is one of the conductive nanowire materials 3, has almost no change in resistance even after the number of bending times exceeding 10. It has sufficient bending resistance. Therefore, as shown in FIG. 5 and FIG. 7A, even when the routing wiring portion 22 is bent along the folding line 23, the resistance value of the bent portion 24 made of the conductive nanowire material 3 does not change. As a result, as shown in FIG. 6 and FIG. 7B, the lead wiring part 22 can be disposed on the side surface of the solar cell unit 1, and the light receiving surface 12 of the solar cell unit 1 can be effectively used for power generation.
以下に、この複合入力装置１０を構成する各構成部材について説明する。 Below, each structural member which comprises this composite input device 10 is demonstrated.
＜タッチパネル部＞
タッチパネル部２は、マトリクス・スイッチ方式、抵抗膜方式、静電容量方式等のいずれの方式によるタッチパネルも使用できる。タッチパネル部２は、入力のための入力面１４を有する。この入力面１４は、太陽電池部１の受光面１２に光を入射するための面としても機能する。なお、タッチ箇所を示すための最下層の表示部分については、例えば、図１０に示す印刷によるボタン１６表示であってもよい。あるいは、タッチパネル部２と太陽電池部１との間に、さらに液晶表示部を備えてもよい。また、タッチパネル部２の透明導電膜４は、導電性ナノワイヤ材料３で構成された折り曲げ部２４を介して太陽電池部１の側面に配置された引き回し配線部２２と電気的に接続されている。
<Touch panel part>
The touch panel unit 2 can use a touch panel of any system such as a matrix switch system, a resistance film system, or a capacitance system. The touch panel unit 2 has an input surface 14 for input. The input surface 14 also functions as a surface for allowing light to enter the light receiving surface 12 of the solar cell unit 1. Note that the lowermost display portion for indicating the touch location may be, for example, the button 16 display by printing shown in FIG. Alternatively, a liquid crystal display unit may be further provided between the touch panel unit 2 and the solar cell unit 1. In addition, the transparent conductive film 4 of the touch panel unit 2 is electrically connected to the lead wiring unit 22 disposed on the side surface of the solar cell unit 1 through a bent unit 24 formed of the conductive nanowire material 3.
＜折り曲げ部＞
折り曲げ部２４によって、タッチパネル部２の透明導電膜４と、太陽電池部１の側面に配置された引き回し配線部２２とが電気的に接続されている。この折り曲げ部２４は、導電性ナノワイヤ材料３によって構成されており、複数回の折り曲げによっても抵抗値変化をほとんど示さない。
<Bending part>
The transparent conductive film 4 of the touch panel part 2 and the lead wiring part 22 arranged on the side surface of the solar cell part 1 are electrically connected by the bent part 24.

<Conductive nanowire material>
FIG. 3 is a schematic diagram showing the structure of a conductive nanowire material 3 having a diameter d and a length L. This conductive nanowire material 3 has an aspect ratio in the range of approximately 10-100,000. In addition, as shown in the 8 mmφ mandrel bending test result of FIG. 4, the transparent conductive film (■) made of a silver nanowire material, which is one of the conductive nanowire materials 3, is resistant even after being bent more than 10 times. It has sufficient bending resistance so that there is almost no change in value.
導電性ナノワイヤ材料３としては、例えば、銀、金、銅、ニッケル、金めっきされた銀、アルミニウム等の金属ナノワイヤ、カーボンナノファイバー、カーボンナノチューブ等の繊維状カーボンを用いることができる。なお、導電性ナノワイヤ材料３としては、上記例示に限定されるものではない。導電性ナノワイヤ材料として、特に銀ナノワイヤが好ましい。 As the conductive nanowire material 3, for example, metal nanowires such as silver, gold, copper, nickel, gold-plated silver and aluminum, and fibrous carbon such as carbon nanofibers and carbon nanotubes can be used. Note that the conductive nanowire material 3 is not limited to the above example. As the conductive nanowire material, silver nanowire is particularly preferable.
なお、導電性ナノワイヤ材料を透明導電材料として用いる提案（特開２０１０−２４４７４７号公報、特表２００９−５０５３５８号公報）がある。 There are proposals (Japanese Patent Application Laid-Open No. 2010-244747, Japanese Translation of PCT International Publication No. 2009-505358) that use a conductive nanowire material as a transparent conductive material.
＜引き回し配線部＞
引き回し配線部２２は、図１及び図２に示すように、太陽電池部１の側面に配置される。この引き回し配線部２２は、上記折り曲げ部２４を介してタッチパネル部２の透明導電膜４と電気的に接続されている。また、引き回し配線部２２は、例えば、銀ペースト等で形成してもよい。

The routing wiring portion 22 is electrically connected to the transparent conductive film 4 of the touch panel portion 2 through the bent portion 24. Moreover, you may form the routing wiring part 22 with a silver paste etc., for example.
なお、引き回し配線部２２の太陽電池部１の側面に接する面に光を反射する反射材を設けてもよい。これによって、太陽電池部１内で散乱光を反射させることができ、発電効率をさらに向上させることができる。 In addition, you may provide the reflecting material which reflects light in the surface which contact | connects the side surface of the solar cell part 1 of the routing wiring part 22. FIG. Thereby, scattered light can be reflected in the solar cell unit 1, and the power generation efficiency can be further improved.
＜太陽電池部＞
