PURPOSE:To shield the light radiation to the bonding resin layer between a glass and a backsheet and to prevent the resin layer from deteriorating by providing an opaque paint layer or a bonding thin film having weather resistance, in the periphery of a surface glass in the form of an edge. CONSTITUTION:A thin-film solar cell element 1 is directly formed under a glass 2, with a periphery margin 20 left, and is covered with a surface resin layer. A backsheet 15 is overlapped with a thermoplastic resin layer 10, an Al foil 11, and an Al foil protective resin layer 12, and covers the solar cell element 1. An air layer 30 is formed in the intermediary between the glass 2 and the backsheet 15. Since the periphery of the backsheet 15 is bonded to the periphery of the glass 2 by thermocompression bonding, the thermoplastic resin layer 10 among the component elements is very thin at the bonding part. A paint layer 40 is provided in the upper periphery of the glass 2. Its width is from the end of the glass 2 to the end at which the thin-film solar cell element 1 is formed. That is, the paint layer 40 is provided in the portion of the periphery where the element 1 is not formed. |
