METHOD FOR PRODUCING RESIN COMPOSITION FOR SOLAR CELL SEALING MATERIAL, RESIN COMPOSITION FOR SOLAR CELL SEALING MATERIAL, SOLAR CELL SEALING MATERIAL, AND SOLAR CELL MODULE |
摘要 |
Disclosed is a method for producing a resin composition for a solar cell sealing material having good storage stability, which enables cost reduction by reducing the processing time. Also disclosed is a solar cell sealing material which is obtained using a resin composition for a solar cell sealing material produced by the method. The solar cell sealing material is free from the formation of bumps and has good transparency. Specifically disclosed is a method for producing a resin composition for a solar cell sealing material, which comprises: a step of preparing, as starting material components, (A) an ethylene-vinyl acetate copolymer that contains a vinyl acetate unit in an amount of 25-35% by weight and (B) a crosslinking agent that has an impregnation weight of 40-80 mg per 24 hours at 23°C with respect to 1 g of the ethylene-vinyl acetate copolymer (A); and a step of impregnating the ethylene-vinyl acetate copolymer (A) with the crosslinking agent (B) at a temperature of 15-80°C. |
