<p>PROBLEM TO BE SOLVED: To provide a nonrigid resin sheet which is excellent in durability, persistently maintains the adhesiveness, and is useful particularly for a solar cell, a filler for a solar cell, a rear sheet for a solar cell, and a solar cell. SOLUTION: This sheet is made of a resin other than an ethylene/vinyl acetate copolymer resin and, when both ends of the sheet are fixed stationary, satisfies the relation of the formula: (σc-σh)<=6×10<4> Pa, whereinσh is a stress occurring between the fixed parts on the ends of the sheet after heating from room temperature Tr to a bonding temperature T1, andσc is a stress between the fixed parts when subsequently cooled from T1 to Tr.</p> |
