SEALING RESIN SHEET AND SOLAR CELL USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a sealing resin sheet capable of simultaneously achieving excellent gap sealability, recyclability, water vapor permeation resistance, and creep resistance while maintaining transparency and adhesiveness.SOLUTION: The solar cell sealing resin sheet contains at least one resin (A) selected from an ethylene-vinyl acetate copolymer and an ethylene-aliphatic unsaturated carboxylic acid copolymer, and a thermoplastic resin (B) other than the resin (A) and an ethylene-aliphatic unsaturated carboxylic acid ester copolymer. The resin (A) has a melt flow rate of 0.3-30 g. The solar cell sealing resin sheet includes an inner layer made of the resin (B) and a surface layer laminated on the inner layer and made of the resin (A).
