NOVELTY - A sealing film is formed by sequentially laminating front-side transparent protection component (11), front-side sealing film (13A), solar battery cells (14), back-side sealing film (13B), and back-side protection component (12). The front-side sealing film contains (in parts mass) ethylene-vinyl acetate copolymer (100), crosslinking agent (1.2-2.5) and ultraviolet absorber (0.015-0.05). The crosslinking agent is 2,5-dimethyl-2,5-di(t-butylperoxy)-hexane. The ultraviolet absorber is 2-hydroxy-4-n-octoxybenzophenone.    USE - Sealing film is used for solar cell (claimed).    ADVANTAGE - The sealing film has excellent external appearance and productivity, and sufficient crosslinking speed, in which the front-side sealing film and cell fixing tape are prevented from yellowing, and bubble formation is suppressed. The solar cell has excellent durability and electric power generation efficiency.    DETAILED DESCRIPTION - A sealing film is formed by sequentially laminating a front-side transparent protection component (11), a front-side sealing film (13A), solar battery cells (14), a back-side sealing film (13B), and a back-side protection component (12). The solar battery cells are temporarily fixed at predetermined positions by cell fixing tapes. The front-side sealing film is used for solar battery in which the solar battery cells are sealed by integrating the sealing film by cross-linking. The front-side sealing film contains (in parts mass) ethylene-vinyl acetate copolymer (100), crosslinking agent (1.2-2.5) and ultraviolet absorber (0.015-0.05). The crosslinking agent is 2,5-dimethyl-2,5-di(t-butylperoxy)-hexane. The ultraviolet absorber is 2-hydroxy-4-n-octoxybenzophenone. An INDEPENDENT CLAIM is included for solar cell.
