Patent ID: 8080727

Claim:
A solar cell module comprising a solar cell layer and a sheet comprising at least one layer of a blend composition of ethylene copolymers, wherein (A) the solar cell layer comprises a single solar cell or a plurality of electrically interconnected solar cells; and (B) the blend composition has a melt flow rate of less than 100 g/10 min, as determined in accordance with ASTM D1238 at 190° C. and 2.16 kg, and comprises: I. about 5 to about 95 wt % of an ethylene copolymer A, based on the total weight of the blend composition, wherein the ethylene copolymer A comprises copolymerized units of ethylene and about 3 to about 20 wt % of a comonomer selected from the group consisting of esters of C 4 -C 8 unsaturated acids having two carboxylic acid groups, anhydrides of C 4 -C 8 unsaturated acids having two carboxylic acid groups, and mixtures thereof, based on the total weight of the ethylene copolymer A; and II. about 5 to about 95 wt % of an ethylene copolymer B, based on the total weight of the blend composition, wherein ethylene copolymer B comprises copolymerized units of ethylene and about 6 to about 40 wt % of at least one polar monomer selected from the group consisting of vinyl acetate, alkyl acrylates, alkyl methacrylates, and mixtures of any two or more thereof, based on the total weight of the ethylene copolymer B, with the proviso that ethylene copolymer A and ethylene copolymer B are chemically distinct.
