PURPOSE: To realize good humidity resistance and weather resistance preventing lowering of characteristic caused by invasion of water by forming adhesive of nylon-12. CONSTITUTION: A first electrode layer 2, a thin film semiconductor layer 3 and a transparent second electrode layer 4 are laminated on a film-like insulation substrate 1, and a third electrode layer 5 is formed in a rear side of the insulation substrate 1. They are fixed by waterproof films 71, 72 with adhesive layers 61, 62 therebetween. The adhesive is formed of nylon-12. The nylon-12 adhesive is thermoplastic resin, which is a hot-melt adhesive. Therefore, it does not generate problems such as yellowing in ethylene vinyl acetate copolymer used before and adhesion strength is also improved. Both humidity resistance and weather resistance of a thin film solar battery are improved. |
