Solar cell sealing materials, and the solar cell sealing sheet and a solar cell using the same

PROBLEM TO BE SOLVED: To provide a solar cell sealing material capable of improving the durability of a solar cell without impairing high transparency, and also maintaining high power generation efficiency for a long period, and to provide a solar cell sealing sheet and a solar cell using the solar cell sealing material. SOLUTION: The solar cell sealing material contains an ethylene-polar monomer copolymer and an epoxy compound having a weight average molecular weight of 200 to 100,000. COPYRIGHT: (C)2011,JPO&INPIT
