PROBLEM TO BE SOLVED: To provide a sealing film for a solar cell, which is capable of reducing gas generation.SOLUTION: Sealing films (13A, 13B) for a solar cell are characterized in that: they contain a resin mixture composed of an ethylene-vinyl acetate copolymer and a polyethylene, and an organic peroxide; the mass ratio (EVA:PE) of the ethylene-vinyl acetate copolymer (EVA) to the polyethylene (PE) in the resin mixture is 8:2 to 3:7; the content of the organic peroxide is 0.1-1.0 part by mass based on 100 parts by mass of the resin mixture; and the gel fraction after crosslinking is 20-80 mass%. |
