Abstract
The present invention provides a solar cell sealing film in which the shrinkage is prevented when heated. The solar cell sealing filmA,B comprises a resin mixture of an ethylene-vinyl acetate copolymer and polyethylene, and an organic peroxide. The mass ratio (EVA:PE) of the ethylene-vinyl acetate copolymer (EVA) to the polyethylene (PE) is 8:2 to 3:7 and the melting point of the resin mixture (temperature at a viscosity of 30,000 Pa·s) is 80 to 105° C.
