<p>PROBLEM TO BE SOLVED: To provide a resin composition for a solar cell sealing material, which comprises an ethyleneα-olefin copolymer, an organic peroxide and others and has high crosslinking property and heat resistance, and to provide a solar cell sealing material and a solar cell module using the resin composition.SOLUTION: The resin composition for a solar cell sealing material comprises an ethyleneα-olefin copolymer component (A) having the following characteristics (a1) to (a2), an organic peroxide component (B), and a hindered amine-based photostabilizer (C). (a1) The density of the copolymer is 0.860 to 0.920 g/cm; and (a2) the total amount of vinyl, vinylidene, cis-vinylene, trans-vinylene, tri-substituted vinylene in the ethyleneα-olefin copolymer is 0.22 (in number per total 1000 carbon atoms) or more, where the number of the vinyl, vinylidene, cis-vinylene, trans-vinylene, and tri-substituted vinylene is a number per total 1000 carbon atoms in a main chain and a side chain measured by NMR.</p> |
