Abstract

PROBLEM TO BE SOLVED: To achieve cost reduction of a solar panel and improvement of convenience at the same time to expand the market.SOLUTION: A wafer is made into a panel without cutting.SELECTED DRAWING: Figure 2

Description

本発明はソーラーパネルの製造法に関する。   The present invention relates to a method for manufacturing a solar panel.

公知のソーラーパネルは、ディスク状のものをほぼ四角形にカットし、つなぎ合わせたものである。この方法では、コストダウンが行き詰まり、もはやこれ以上下がらない。 A known solar panel is obtained by cutting a disk-like thing into a substantially square shape and joining them together. With this method, the cost reduction is stuck and no longer decreases.

図１はこのような光電変換素子作成の工程を示す図である。１は光電変換素子がくまなく配置されたウエハである。この光電変換素子としては、例えば単結晶シリコン，多結晶シリコン，アモルファスシリコン等が用いられる。     FIG. 1 is a diagram showing a process for producing such a photoelectric conversion element. Reference numeral 1 denotes a wafer on which photoelectric conversion elements are arranged. As this photoelectric conversion element, for example, single crystal silicon, polycrystalline silicon, amorphous silicon, or the like is used.

（ａ）に示すウエハは、（ｂ）に示すように所定の大きさの矩形２に切り取られる。ウエハ１から矩形の光電変換部２が切り取られた残りの部分（ハッチング領域）は廃棄処分される。最終的には、（ｃ）に示す矩形のユニットを集合させて矩形パネル３を製作する。３ａは光電変換ユニットを構成する１つ一つの光電変換素子である。   The wafer shown in (a) is cut into a rectangle 2 having a predetermined size as shown in (b). The remaining portion (hatched area) from which the rectangular photoelectric conversion unit 2 is cut out from the wafer 1 is discarded. Finally, rectangular units 3 shown in (c) are assembled to produce the rectangular panel 3. 3a is each photoelectric conversion element which comprises a photoelectric conversion unit.

上述した公知のソーラーパネルでは、ウエハに無駄を生じ、カットのコストもかかり、しかも太陽光を透過することができないため、ソーラーパネルの有効利用が限定される。コストダウン競争ではもはやこれ以上下げることができない。
本発明はこのような課題に鑑みてなされたものであって、ソーラーパネルを合理的にこれ以上ローコストにし、且つ同時に利用範囲を拡げられないので、マーケットが拡がるソーラーパネルを提供することを目的としている。 In the known solar panel described above, the wafer is wasted, cutting costs are incurred, and sunlight cannot be transmitted, so that the effective use of the solar panel is limited. Cost reduction competition can no longer reduce it.
The present invention has been made in view of such problems, and it is intended to provide a solar panel that expands the market because the solar panel can be made reasonably low cost and the range of use cannot be expanded at the same time. Yes.

本発明は、ウエハをそのまま光電変換ユニットとして使用する。つまり、図２に示すようにウエハ１をそのまま敷き詰めてそのままソーラーパネルとした。この結果、カットのコストが不要となり、またパネル面でソーラーパネル内の納期早め製造のコストダウンと利便性の向上を同時に行える。また、ウエハをカットしないので、その分、大きなコストダウンができる。この結果、透明な領域５が形成される。図では１個しかハッチング領域５を示していないが、他の領域も全く同一である。
ソーラーパネル内納期早め製造のコストダウンと利便性の向上を同時に行える。ウエハをカットしないのみならず、その分大きなコストダウンができる。 In the present invention, a wafer is used as it is as a photoelectric conversion unit. That is, as shown in FIG. 2, the wafer 1 was spread as it was to obtain a solar panel. As a result, the cost of cutting is not required, and the cost of manufacturing and the convenience of manufacturing can be reduced at the same time by shortening the delivery date in the solar panel. Further, since the wafer is not cut, the cost can be greatly reduced. As a result, a transparent region 5 is formed. Although only one hatched area 5 is shown in the figure, the other areas are exactly the same.
It is possible to reduce the manufacturing cost and improve the convenience at the same time in the solar panel. In addition to not cutting the wafer, the cost can be reduced accordingly.

ソーラーパネルに照射した日光の一部９は透明領域５を突きぬけて、図３の９に示すようにソーラーパネルを突き抜ける。１は光電変換素子部分である。縦と天窓が図４に示すように縦窓に使用でき、発電と採光が同時にできる。また図５に示すように屋根に設ければ、図３に示すようにソーラーパネルの裏側でこの透過した日光を利用して温水化、野菜の栽培等を行うことができ、ソーラーパネル加工がローコストで製造でき、製造時間も短縮できる上、ソーラーパネルの有効利用を図ることができる。   A part 9 of sunlight irradiated on the solar panel penetrates the transparent region 5 and penetrates the solar panel as shown by 9 in FIG. Reference numeral 1 denotes a photoelectric conversion element portion. Vertical and skylights can be used for the vertical window as shown in FIG. Further, if it is provided on the roof as shown in FIG. 5, it is possible to perform warming, vegetable cultivation, etc. using the transmitted sunlight on the back side of the solar panel as shown in FIG. In addition to reducing the manufacturing time, the solar panel can be effectively used.

以下、図面を参照してその他の本発明の実施例を詳細に説明する。図５は本発明の実施例３の説明図である。ソーラーパネル４の下には水を循環させるための部分７が配置されている。ソーラーパネル４には、図２の５に示すような透明部が開けられている。
ソーラーパネル４の下へ流入された水８はパネル下７を通過する間に熱せられて温水になる。なお、光電素子１は冷やされると光電変換特性が向上することが知られているので、一石二鳥を得ることができる。加熱により温水となった水は※ダクト１０を介して下向きに流れ貯留槽１１に溜める。この貯留槽１１に溜め込んだ温水は、例えば床暖房や、キッチン用の温水として用いることができる。 Hereinafter, other embodiments of the present invention will be described in detail with reference to the drawings. FIG. 5 is an explanatory diagram of Embodiment 3 of the present invention. A portion 7 for circulating water is disposed under the solar panel 4. The solar panel 4 has a transparent portion as shown in FIG.
The water 8 flowing under the solar panel 4 is heated while passing through the lower panel 7 to become warm water. In addition, since it is known that when the photoelectric element 1 is cooled, photoelectric conversion characteristics are improved, two birds with one stone can be obtained. The water that has been heated by heating flows downward through the duct 10 and accumulates in the storage tank 11. The hot water stored in the storage tank 11 can be used, for example, as floor heating or hot water for a kitchen.

図６は本発明の実施例４の説明図である。図１と同一のものは、同一の符号を付して示す。図において、１２は地面である。この地面１２には野菜１３が栽培されている。この野菜面には、ソーラーパネル１の透明部５を通過した日光９が入射される。日光が十分でない状況下でも十分に生育できる野菜は存在するので、ソーラーパネルの発電の収益と採光による野菜の収益が加算される。   FIG. 6 is an explanatory diagram of Embodiment 4 of the present invention. The same components as those in FIG. 1 are denoted by the same reference numerals. In the figure, 12 is the ground. Vegetables 13 are cultivated on the ground 12. Sunlight 9 that has passed through the transparent portion 5 of the solar panel 1 is incident on the vegetable surface. Since there are vegetables that can grow well even in situations where sunlight is not enough, the revenue from solar panel power generation and the revenue from vegetables from lighting are added.

また、ソーラーパネルの下にＬＥＤ１４を設け、ソーラーパネル４の発電と発光させれば、発電が促進される。また、日光が十分でない状況下でも十分に生育できる野菜は存在するので、これら野菜を栽培することができる。この種の野菜としては、例えばアスパラガス，イチゴ，ウド，エンドウ，ホウレンソウ等が適当である。
図７は公知のソーラーパネルの横断面を示し、表面がガラス１５、カットされた光電ウエハ３ａ、バックシート１６、枠１８からなる。 Moreover, if LED14 is provided under a solar panel and it is made to light-emit with the electric power generation of the solar panel 4, electric power generation will be accelerated | stimulated. In addition, since there are vegetables that can grow sufficiently even under conditions where sunlight is not sufficient, these vegetables can be cultivated. As this kind of vegetables, for example, asparagus, strawberry, udo, pea, spinach and the like are suitable.
FIG. 7 shows a cross section of a known solar panel, which is composed of a glass 15, a cut photoelectric wafer 3a, a back sheet 16, and a frame 18.

図８は本発明ソーラーパネルの実施例５の横断面を示し、透明ガラスのバック
板の上に円形光電ウエハ１を載せたものであり、光を通し、バックシート１６もなく、枠１８もないので、ローコストで製造も速く、且つ軽量であるので、屋根に載せるのに適している。前記透明ガラスバック板１９は、ポリカーボネートであれば軽量化できる。 FIG. 8 shows a cross section of Example 5 of the solar panel of the present invention, in which a circular photoelectric wafer 1 is placed on a transparent glass back plate, passes light, and there is no back sheet 16 and no frame 18. Therefore, it is suitable for mounting on the roof because it is low-cost, fast to manufacture, and lightweight. The transparent glass back plate 19 can be reduced in weight if it is polycarbonate.

図９は本発明ソーラーパネルの実施例６の横断面図で、表面ガラス１５の下に円形光電ウエハ１を設け、その下に透明なバックシート透明バックシート１７を設けて光を透過させる構造にしたものである。   FIG. 9 is a cross-sectional view of a solar panel according to a sixth embodiment of the present invention, in which a circular photoelectric wafer 1 is provided under the surface glass 15, and a transparent backsheet transparent backsheet 17 is provided thereunder to transmit light. It is a thing.
