<P>PROBLEM TO BE SOLVED: To provide a rear surface protecting sheet for a solar cell which has long-term durability against severe natural environment being excellent in heat resistance, weather resistance, water resistance, damp-proofing, wind pressure-proof property, hailstorm-proof property, chemical resistance, antifouling property, light reflective property, optical diffusivity, and other properties; and makes it possible to maintain output power and to extend life. <P>SOLUTION: In the rear surface protecting sheet for solar cell of a laminated body; an inside substrate layer, an intermediate barrier layer, and an outside substrate layer are sequentially laminated through an adhesion layer. The protecting sheet is composed of a base material film or a sheet of chlorine system resin or fluorine system resin, in which a polyvinylalcohol layer is formed at least in one side of the intermediate barrier layer. <P>COPYRIGHT: (C)2008,JPO&INPIT |
