ABDECKMATERIAL FÜR SOLARZELLE

摘要

A covering member is used as a transparent protective member for protecting solar cells of a solar battery. The covering member includes a transparent high-sunproof film, a transparent high-moistureproof film laminated on the transparent high-sunproof film, and ethylene-vinyl acetate copolymer adhesive disposed between the transparent high-sunproof film and the transparent high-moistureproof film. The high-moistureproof film is formed of two transparent polyethylene terephthalate films and inorganic oxide coatings coated on the respective films. The inorganic oxide coatings are formed of silica and/or alumina, and coating surfaces thereof are bonded to each other. The ethylene-vinyl acetate copolymer adhesive contains ultraviolet absorbing agent and organic peroxide as a cross-linking agent.
