Abstract

The invention relates to a double-layer solar cell module packaging adhesive film which is compounded from an EVA (ethylene-vinyl acetate) adhesive film outer layer and an EVA adhesive film inner layer. The EVA adhesive film outer layer is prepared from 100 parts of ethylene-vinyl acetate resin, 0.4-2.0 parts of peroxide crosslinking agent, 0.1-1.5 parts of tackifier, 0.01-0.5 part of antioxidant and 0.05-1.0 part of modifier. The EVA adhesive film inner layer is prepared from 100 parts of ethylene-vinyl acetate resin and 0.4-2.0 parts of peroxide crosslinking agent. The adhesive film is compounded by coextruding the EVA adhesive film outer layer and EVA adhesive film inner layer; and by using the complete formula system, the adhesive film has excellent bonding property and aging resistance, effectively prevents the component from PID (proportion integration differentiation) phenomenon, and has favorable bonding property with glass. The matching degree with the cell, solder strip, soldering flux, silver paste and the like is enhanced.
