Abstract
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 CH═C(R)COR, and a second olefin having the formula CH═C(R)COOH. The second ethylene copolymer consists essentially of copolymerized units of ethylene, optionally a first olefin having the formula CH═C(R)COR, and a third olefin having the formula CH═C(R)D. R, Rand Rrepresent hydrogen or an alkyl group; Rrepresents 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 acid groups of the second olefin have reacted with some epoxy groups of the third olefin.
