RESIN COMPOSITION FOR SOLAR CELL SEALING MATERIAL, SOLAR CELL SEALING MATERIAL MANUFACTURED THEREFROM, AND SOLAR BATTERY MODULE

摘要

PROBLEM TO BE SOLVED: To provide: a resin composition for solar cell sealing material which contains an ethylene/α-olefin copolymer, an organic peroxide, etc., and has good crosslinking characteristic and good heat resistance; a solar cell sealing material manufactured from such a resin composition; and a solar battery module manufactured therefrom.SOLUTION: A resin composition for solar cell sealing material comprises: an ethylene/α-olefin copolymer component (A) having the characteristics (a1) and (a2) below; an organic peroxide component (B); and a hindered-amine based optical stabilizer (C). (a1)The density is 0.860-0.920 g/cm; and (a2)the total number (N) branches derived from comonomer in the ethylene/α-olefin copolymer is 54-95(/total 1000C)(where N is a number per 1000 carbon atoms of main and side chains in total as measured by NMR).
