摘要：Provided herein is a blend composition useful as a cross-linkable encapsulant layer and consisting essentially of two ethylene copolymers and optionally one or more additives. The first ethylene copolymer comprises copolymerized units of ethylene, optionally a first olefin having the formula CH2&boxH;C(R1)CO2R2, and a second olefin having the formula CH2&boxH;C(R3)COOH. At least a portion of the carboxylic acid groups have been neutralized to form carboxylate salts. The second ethylene copolymer consists essentially of copolymerized units of ethylene, optionally a first olefin having the formula CH2&boxH;C(R1)CO2R2, and a third olefin having the formula CH2&boxH;C(R4)D. R1, R3 and R4 represent hydrogen or an alkyl group; R2 represents an alkyl group; and D represents a moiety containing an epoxy group. Further provided are solar cell modules comprising the encapsulant layer. The encapsulant layer comprises the blend composition or the product of cross-linking the blend composition, in which some carboxylate groups of the second olefin have reacted with some epoxy groups of the third olefin.
