本発明は直並列接続された太陽電池素子から組立てられ

The surface of the photoelectric conversion semiconductor layer 1 of the solar cell element formed thereon is covered with a protective resin layer 3, and a photovoltaic force is generated by light 4 incident from the side of the glass plate 2.

ステンレスなどの金属が使用されていた。In a solar cell module assembled from a plurality of such solar cell elements, reinforcement of the mechanical strength of the module,
It is necessary to provide a frame 6 around the periphery in order to hold the sealant 5 and fix it to the pedestal. The frame 6 of the solar cell module basically has the same required functions as a general architectural glass frame, and is structurally designed so that the module can withstand wind pressure at an instantaneous maximum wind speed of 60 m/see. In this structural design, as shown in FIG. 1, the cross section of the frame 6 has a U-shape, and conventionally, metals such as aluminum and stainless steel have been used as the material.

を避けるためには、影となるおそれがある部分には光電
変換半導体層１を構成することができない。Conventional solar cell module frames have the following drawbacks. That is, since a portion is created that is a shadow of the incident light 4 due to the frame 6 extending above the glass plate 2, no photovoltaic force is generated in the photoelectric conversion semiconductor layer 1 in that portion, but photovoltaic force is generated in other portions. Because a reverse current flows due to the generated electromotive force, there is a risk of deterioration of the solar cell element. In order to avoid this risk, the photoelectric conversion semiconductor layer 1 cannot be formed in a portion that is likely to be shaded.

0C1l! When an aluminum frame 6 with a width of 1 crn is installed in a solar cell module, the light shielding surface area occupied by the frame is 196 cJ, and this alone reduces the practical conversion efficiency by about 8%. This reduction in efficiency becomes even greater when considering the shadow area when the light is incident.

A transparent sealing material may be interposed between the frame and the solar cell element.

換面積を増大させることができる。2 and 3 are cross-sectional views of solar cell modules showing two different embodiments of the present invention, and parts common to those in FIG. 1 are given the same reference numerals. The difference between FIG. 2 and FIG. 1 is that it is not made of transparent plastic, and a frame 16 with a U-shaped cross section is attached to the periphery of the module via a transparent acrylic thread sealant 15. In this case, since the light energy can pass through the transparent plastic frame 16 and the transparent acrylic sealant 15, the photoelectric conversion semiconductor layer 1 made of, for example, amorphous silicon can be provided on the entire surface of the glass plate 2. , the photoelectric conversion area can be increased.

半導体層１をガラス板１の全面に設けることができる。In FIG. 3, the frame 16 is made of transparent plastic, but the sealing member 25 is made of an opaque sealant such as black butyl rubber. However, the photoelectric conversion semiconductor layer 1 can be provided on the entire surface of the glass plate 1 as in the case of FIG. 2 by filling the sealing material 25 in such a manner that the light-receiving surface side of the module is not dented.

Of course, it can also be implemented in the case where the light is incident on the ground.

ｌＩＪ積の２％にとどまる・In the present invention, by forming the frame surrounding the solar cell module from a transparent Hiko material, the lower part of the frame can also be used for photoelectric conversion. Therefore, even if the total light-receiving area of the solar cell module is the same as before, by increasing the area of the part that has photoelectric conversion function, the maximum output can be increased and the practical conversion efficiency (module efficiency) of the solar cell module can be improved. . For example, if a plastic frame with a thickness of 3 m including the sealing material is used in the aforementioned solar cell module with dimensions of 50 x 50 cm, the area that is not useful for photoelectric conversion out of the module's total light-receiving area of 2,500 ffl is 50 i.
