PROBLEM TO BE SOLVED: To provide a method for manufacturing a sealing film for solar cell capable of manufacturing a sealing film for solar cell, where sneaking is less likely to occur while manufacturing a solar cell, excellently without leaving an unmelted portion.SOLUTION: In a method of manufacturing a sealing film 13B for solar cell including a step for kneading and molding an ethylene-vinyl acetate copolymer, polyethylene, an organic peroxide and a coloring agent, the kneading is performed at X°C, a low temperature decomposition organic peroxide A having a 10-hour half life of a°C, and a high temperature decomposition organic peroxide B having a 10-hour half life of b°C are used as the organic peroxide. The X°C, a°C and b°C satisfy the relation of following formulae; :a°C<X°C-30°C(I), b°C>X°C-20°C(II), and the blending quantity of the low temperature decomposition organic peroxide A is 0.05-1.0 pts.mass for the total quantity 100 pts.mass of the ethylene-vinyl acetate copolymer and polyethylene. |
