Abstract
The object of the present invention to provide a solar cell sealing film comprising chiefly ethylene-vinyl acetate copolymer, organic peroxides for giving crosslinked structure, which suppresses occurrence of blister without reduction of crosslink rate, even if the film contains silane-coupling agents for improving adhesive strength. The solar cell sealing film comprising 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.
