<p><P>PROBLEM TO BE SOLVED: To provide a rear surface protective sheet for a solar cell, capable of preventing delamination between layers, even if the sheet is used outdoors over a long term, in a configuration where a plurality of layers are laminated via adhesive layers, and to provide a solar cell module that uses the sheet. <P>SOLUTION: The rear-surface protective sheet for the solar cell is such that weather resistance film layers are laminated via the adhesive layers on both the surfaces of a base material layer. When the adhesive layers are measured according to the D635 Testing Method of ASTM (American Society for Testing and Materials), each adhesive layer comprises an adhesive film, where the numerical value of extension with a dumbbell shape 4 test piece is 400-1,000%. The adhesive film includes, at least a polycarbonate-based resin, an acrylic resin, or a polystyrene-based resin, and the solar cell module is made as a unit by using the rear-surface protective sheet for the solar cell. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
