SOLAR CELL MODULE
A solar cell module includes a solar cell, a light-receiving surface member on a light-receiving side of the solar cell, a rear surface member on a rear side of the solar cell, and a sealing material between the light-receiving surface member and the rear surface member. The rear surface member has higher permeability of acetic acid than that of the light-receiving surface member. The sealing material seals the solar cell and includes a light-receiving side sealing material on the light-receiving side of the solar cell and a rear side sealing material on the rear side of the solar cell. The light-receiving side sealing material does not contain an ethylene-vinyl acetate copolymer. The rear side sealing material contains the ethylene-vinyl acetate copolymer.
