Abstract
The present invention provides a solar cell module comprising a terionomer containing film or sheet, wherein the terionomer is derived from an acid terpolymer that comprises copolymerized units derived an α-olefin, about 15 to about 30 wt % of an α,β-ethylenically unsaturated carboxylic acid having 3 to 8 carbons, and about 0.5 to about 40 wt % of an α,β-ethylenically unsaturated carboxylic acid ester having 4 to 12 carbons, based on the total weight of the acid terpolymer, and is about 5% to about 90% neutralized with one or more metal ions, based on the total carboxylic acid content of the acid terpolymer.
Claims25
A solar cell pre-lamination assembly comprising (i) a solar cell component formed of one or a plurality of electronically interconnected solar cells and having a light-receiving side that faces a light source and a back side that is opposite from the light source and (ii) a film or sheet comprising or made of a terionomer composition, wherein the terionomer is derived from an acid terpolymer that comprises copolymerized units derived from an α-olefin, about 15 to about 30 wt % of an α,β-ethylenically unsaturated carboxylic acid having 3 to 8 carbons, and about 0.5 to about 40 wt % of an α,β-ethylenically unsaturated carboxylic acid ester having 4 to 12 carbons, based on the total weight of the acid terpolymer, and has about 5% to about 90% of its carboxylic acid content neutralized with one or more metal ions.
