摘要:
The object of the present invention is to provide a solar cell sealing film obtained from a composition comprising chiefly ethylene-vinyl acetate copolymer and organic peroxides for giving crosslinked structure, which suppresses the occurrence of blisters without reduction of crosslink rate, even if the film contains silane-coupling agents for improving adhesive strength. The solar cell sealing film comprises ethylene-vinyl acetate copolymer, an organic peroxide, a silane-coupling agent, and a phosphite compound represented by formula (I): P(OR1)3 (I) wherein, R1 is a branched-chain aliphatic alkyl group having 8 to 14 carbon atoms, and three R1s are the same as or different from each other and further wherein the content of the vinyl acetate recurring unit of the ethylene-vinyl acetate copolymer is in the range of 20 to 35% by weight.
