[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar cell device which can be carried to a required place and used.

[0002]

2. Description of the Related Art In a solar cell device which takes power by carrying it to a required place, it is necessary to make it difficult for vibrations and shocks applied during transportation to be transmitted to the solar cell. In particular, a solar cell using a glass substrate may be easily broken by vibration or impact.

Various attempts have been made to avoid such a problem. For example, Japanese Utility Model Laid-Open Publication No. Sho 62-36558 discloses that a sealing material is filled between a solar cell and a frame-shaped case (frame). doing. The technology disclosed in this publication is
In FIG. 1, the solar cell is in direct contact with the frame-shaped case because the primary purpose is to improve the waterproofness. However, in order to absorb vibrations, the solar cell shown in FIGS. As shown, it is better that the solar cell and the frame-shaped case are separated from each other. However, in order to fill the sealing material with the solar cell and the frame case separated from each other, it is necessary to support the solar cell with something at the time of filling, and it is difficult to perform the work. It may protrude to the surface of the battery and impair its beauty.

[0004]

SUMMARY OF THE INVENTION The present invention eliminates the need to provide a means for supporting a solar cell when a resin is filled in a frame-shaped case. It is intended to not protrude.

[0005]

According to the present invention, an elastic adhesive tape is attached to an edge of a frame-shaped case, and a solar cell is temporarily fixed to the adhesive tape. It is to be filled.

[0006]

By temporarily fixing the solar cell to the rim of the frame-shaped case with an adhesive tape, special means for supporting the solar cell at the time of filling the resin is not required, and the frame is not required. When the resin is filled into the case, the adhesive tape acts as a weir, so that the resin does not protrude to the surface of the solar cell.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, reference numeral 1 denotes a frame-shaped case, and an elastic double-sided adhesive tape 2 made of butyl rubber is adhered to the edge of the case. Reference numeral 3 denotes a solar cell, which is temporarily fixed by pressing the peripheral portion against the adhesive tape 2,
Thereafter, the frame-shaped case 1 was filled with a polyurethane resin and heated to obtain an elastic resin 4. Further, the back cover 5 was attached with an adhesive or a screw to form a solar cell.

The double-sided adhesive tape 2 made of butyl rubber has a 40 ° JIS. A having a hardness of 55 to 70 ° JIS. A was used. The solar cell 3 has a size of 350 × 150 m.
An amorphous silicon solar cell is formed on a glass substrate having a thickness of 1.8 mm and a thickness of 1.8 mm.
Is made of polycarbonate resin. When a drop test was performed using this solar cell device, no problem was found up to 1.2 m. On the other hand, when the solar cell 3 was in direct contact with the frame case 1, the limit was 0.6 m.

[0009]

As described above, in the present invention, the elastic adhesive tape is attached to the rim of the frame-shaped case, the solar cell is temporarily fixed thereto, and then the elastic resin is filled. It is possible to provide a solar cell device in which a battery does not hit a hard frame-shaped case and is resistant to vibration and impact. In addition, since the solar cell is temporarily fixed with an adhesive tape, there is no need to separately provide a means for supporting the solar cell when filling the elastic resin, which is excellent in mass productivity, and furthermore, the elastic resin is filled. When the adhesive tape acts as a weir, without the resin protruding to the surface of the solar cell,
There is no loss of beauty.
