PROBLEM TO BE SOLVED: To realize easy recovery from output drop caused by temperature change and to suppress fluctuation, relating to a solar cell module, especially to a back contact type solar cell module.SOLUTION: A sealing film for a solar cell contains a polymer component selected from groups comprised of an ethylene/α-olefin/diene copolymer and an ethylene/α-olefin copolymer as well as a crosslinking agent. An electrification attenuation time of a sheet obtained by heating the sealing film for the solar cell at 150°C for 10 minutes is 9000 seconds or longer when measured with an applied voltage of 500 V at 100°C based on JIS K6911. |
