RESIN COMPOSITION FOR SOLAR CELL SEALING MATERIALS

摘要

To provide a resin composition for a solar cell encapsulant material, comprising features of containing: 5 to 30% by weight of ethylene-unsaturated fatty acid ester copolymer (A) having a crystal melting peak temperature of 95 to 110°C as measured at a heating rate of 10°C/min in differential scanning calorimetry and containing 10 to 23% by weight of unsaturated fatty acid ester; and 95 to 70% by weight of at least one kind of copolymer (B) selected from ethylene-olefin random copolymer (b-1) having a crystal melting peak temperature lower than 80°C and copolymer (b-2) obtained by copolymerizing alkoxysilane having a polymerizable functional group and the ethylene-olefin random copolymer (b-1).
