合しないという問題点がある。In the case of the conventional, the impact of falling objects such as hail and stone,
The solar cell element (3) is easily cracked, and the slate roof tile (1) itself has sufficient impact resistance when subjected to an impact test based on the "JIS A 1421-1981" Method of impact test for building boards ". However, since the solar cell element (3) is damaged, the above-mentioned standard cannot be satisfied, and there is a problem that it does not conform to the JIS standard as a building material for a roof.
本発明は、前記の点に留意してなされ、JIS規格に基

いようにし、JIS規格に適合した屋根用建材としての太
陽電池を提供することを目的とする。The present invention is made in consideration of the above points, so that the solar cell element is not damaged even when an impact test based on the JIS standard is performed, and a solar cell as a roofing building material conforming to the JIS standard is provided. The purpose is to:
前記目的を達成するために、本発明は、屋根に設置さ

記充填層上に形成された透明耐候性フィルムとを備えた
太陽電池であって、 前記充填層と前記耐候性フィルムとの間に透明緩衝層
を設けたことを特徴とするものである。In order to achieve the above object, the present invention provides a solar cell including a solar cell element embedded in a filling layer on a substrate installed on a roof, and a transparent weather-resistant film formed on the filling layer. Wherein a transparent buffer layer is provided between the filling layer and the weather-resistant film.
以上のように構成された本発明の太陽電池は、充填層

落下物の衝撃が緩和され、従来に比べて耐衝撃性が大幅
に向上した屋根用建材としての太陽電池を提供できる。In the solar cell of the present invention configured as described above, since the transparent buffer layer is provided between the filling layer and the transparent weather-resistant film, the buffer layer allows the falling object to fall on the light incident side of the solar cell element. It is possible to provide a solar cell as a building material for a roof in which the impact is reduced and the impact resistance is greatly improved as compared with the related art.
１実施例について第１図を参照して説明する。 One embodiment will be described with reference to FIG.

ム，ポリカーボネイト系樹脂等からなる透明緩衝層
（６）を設けた点である。In this figure, the same symbols as those in FIG. 3 indicate the same or corresponding parts, and the difference from FIG. 3 is that silicon rubber and polycarbonate are provided between the EVA filling layer (2) and the PET film (4). This is the point that a transparent buffer layer (6) made of a system resin or the like is provided.
このとき、透明緩衝層（６）は厚い程緩衝効果が高く
なるが、厚くしすぎると入射光の減衰が大きくなりす
ぎ、太陽電池素子（３）への入射光量が減つて発電効果
が低下するなどの不都合が生じるため、最大3mmの厚さ
が適当である。At this time, the buffering effect increases as the thickness of the transparent buffer layer (6) increases. However, if the thickness is too large, the attenuation of the incident light becomes too large, and the amount of light incident on the solar cell element (3) decreases, thereby reducing the power generation effect. For this reason, a maximum thickness of 3 mm is appropriate.
また、透明緩衝層（６）の屈折率は、太陽電池素子
（３）への入射光量を確保できるように1.3〜1.6が適当
であり、これより屈折率が大きいと、緩衝層（６）での
反射が大きくなつて入射光量が減少する。Further, the refractive index of the transparent buffer layer (6) is suitably from 1.3 to 1.6 so as to secure the amount of light incident on the solar cell element (3). Increases the amount of incident light.
そして、この太陽電池を作成する手順としては、スレ

ト瓦（１）とを一体化できる。The procedure for producing this solar cell is as follows: an EVA serving as a filling layer (2) is stacked on a slate roof tile (1), a solar cell element (3) is stacked thereon, and an EVA is further stacked, and a transparent buffer layer is stacked. After sequentially stacking the silicon rubber for (6) and PET, the whole of them is laminated at 10 -3 Torr by a laminating apparatus.
Heating may be performed at 150 ° C. for about 40 minutes in the vacuum described above, whereby the solar cell element (3) and the slate roof (1) can be integrated as shown in FIG.

験を行つたところ、太陽電池素子（３），スレート瓦
（１）とも破損することがなく、屋根用建材としてJIS
規格を満足することができる。By the way, an amorphous silicon solar cell element formed on a 1.1 t glass substrate was used as the solar cell element (3), and a 1 mm-thick silicon rubber was used for the buffer layer (6).
Assuming that the thickness of the film (4) is 100 μm, JIS A 1421-1
When an impact test was conducted in accordance with 981 "Method of impact test for building boards", neither solar cell element (3) nor slate tile (1) was damaged, and JIS was used as a roof building material.
Standards can be satisfied.
