Abstract
A solar cell module comprising a solar cell layer and a sheet comprising at least one layer of a sodium ionomer composition, wherein the sodium ionomer composition consists essentially of a sodium ionomer that is an ionic, neutralized derivative of a precursor α-olefin carboxylic acid copolymer, wherein about 10% to about 35% of the total content of the carboxylic acid groups present in the precursor α-olefin carboxylic acid copolymer have been neutralized with sodium ions, and wherein the precursor α-olefin carboxylic acid copolymer comprises (i) copolymerized units of an α-olefin having 2 to 10 carbons and (ii) about 20 to about 25 wt %, based on the total weight of the α-olefin carboxylic acid copolymer, of copolymerized units of an α,β-ethylenically unsaturated carboxylic acid having 3 to 8.
