Multi-layer sheet for solar cell sealant, method for manufacturing multilayer sheet for solar cell sealant, and solar cell module

摘要

The multilayer sheet 10 for a solar cell sealing material of the present invention is used for sealing a solar cell element and comprises a resin layer (A) containing an ethylene / unsaturated carboxylic acid copolymer or an ionomer thereof as a main component and a resin layer ) Or an adhesive layer (B) provided on one side or both sides of the adhesive layer (B). Then, the adhesive layer (B) is an epoxy group-containing ethylene-based copolymer (B1) and the ethylene-polar monomer copolymer and a density of 920kg / m ³ or less, ethylene-based copolymer of ethylene and at least one selected from α- olefin copolymer (B2) (except for the epoxy group-containing ethylenic copolymer (B1)).
