Patent ID: 7449629

Claim:
A solar panel comprising: a front panel; a photovoltaic material layer deposited either directly on the front panel or directly on an anti-reflective coating formed between the front panel and the photovoltaic material layer; a backing panel; an adhesive layer adhering the photovoltaic material layer to the backing panel; wherein the adhesive layer comprises an adhesive composition, the adhesive composition comprising a low MVTR polymer or copolymer and a silane-modified polymer or copolymer, wherein the silane-modified polymer or copolymer is provided to the adhesive preformed and is different from the low MVTR polymer or copolymer; and wherein the silane-modified polymer or copolymer is a silane-crosslinkable halogenated polymer composition comprising a mixture of 100 parts by weight of a halogenated polymer and about 0.1 to about 20 parts by weight of an amino group-containing silane compound having the following general structure: RHNR′Si(OR″) 3 wherein R is hydrogen, an alkyl or a phenyl group, R′ is an alkylene group, OR″is an alkoxy or alkoxyalkoxy group having 1 to 6 carbon atoms.
