構造とすることができる。In the solar cell device of the present invention, since the output voltage of the solar cell element 1 is as low as about 0.45 V, a large number of solar cell elements 1 connected in series (cell string) using ink-connector leads 2 are connected to an appropriate location on the light-receiving surface side. A filler material 4 is placed between the tempered glass 3 having a high transmittance and the backing material 5 made of synthetic resin.
In this structure, the periphery is sealed by an elastic body 7 via an adhesive 6, and the outside of the elastic body 7 is further protected by a metal frame 8. The main fillers 4 include polyvinyl butyral 1 (PVB), ethylene-vinyl acetate copolymer, etc., and the backing materials 5 include:
Examples of metal frames include vinyl fluoride film, 41% ethylene-hexafluoride propylene, and polyethylene tereftate, such as aluminum and stainless steel. In this practical example, PVB was used as the filler 4, vinyl fluoride film was used as the backing material 5, alumite-treated aluminum was used as the metal frame, and ethylene-propylene rubber (E, P, M) was used as the elastic body 7. This structure allows
External force applied between the light-receiving surface tempered glass 3 and the metal frame 8 (
For example, thermal displacement due to temperature difference, external force due to strong winds such as during typhoons) are not applied directly to the adhesive 6, but are applied to the elastic body (E,
P, M) absorbed by 7. In addition, E, P, and M are the same materials used to seal automobile windshields, and they have excellent sealing effects, so by incorporating them into solar cell devices, solar cell elements and filling materials can be completely protected from outside air. It is possible to provide a good structure in terms of weather resistance.
なお、この実施例において、金属フレーム８を省いて、
弾性体７をその代用としてもよい。それにより、重量、
工数、原価の低減に効果がある。In addition, in this embodiment, the metal frame 8 is omitted,
The elastic body 7 may be used instead. As a result, the weight,
Effective in reducing man-hours and costs.
