Abstract:
A sealing film for a solar cell is provided, which has excellent ultraviolet resistance. The sealing film for a solar cell according to the present invention includes ethylene-vinyl acetate copolymer; an organic peroxide; a benzotriazole-based ultraviolet absorber; and a hindered amine-based light stabilizer. The content of the benzotriazole-based ultraviolet stabilizer is in the range of 0.01 to 0.3 parts by weight, based on 100 parts by weight of ethylene-vinyl acetate copolymer. Further, the content of the hindered amine-based light stabilizer is in the range of 0.01 to 2 parts by weight, based on 100 parts by weight of ethylene-vinyl acetate copolymer.
