Abstract
A concentrator solar cell module comprises at least one solar cell and at least one light concentrating article. The at least one light concentrating article is capable of concentrating about 1.02 to about 2000 sun equivalents of solar energy onto the solar cell(s) and comprises an ionomer composition. The ionomer composition comprises or is produced from an ionomer that has a temperature of onset of creep that is significantly greater than its peak melting temperature.

15. A concentrator solar cell module comprising one or a plurality of solar cells and at least one light concentrating article, wherein,
(A) the light concentrating article is capable of concentrating about 1.02 to about 2000 suns of solar energy onto the solar cells; (B) the at least one light concentrating article comprises an ionomer composition, and the ionomer composition comprises or is prepared from an ionomer;
the ionomer comprises carboxylate groups and cations and is the product of a neutralization of a precursor α
-olefin carboxylic acid copolymer;
the precursor α
-olefin carboxylic acid copolymer comprises (i) copolymerized units of an α
-olefin having 2 to 10 carbons and (ii) about 18 to about 30 wt % of copolymerized units of an α
,β
-ethylenically unsaturated carboxylic acid having 3 to 8 carbons, based on the total weight of the α
-olefin carboxylic acid copolymer; and
about 5% to about 90% of the total content of the carboxylic acid groups present in the precursor α
-olefin carboxylic acid copolymer are neutralized to form the ionomer.- View Dependent Claims (16, 17, 18, 19, 20)
