Abstract
Disclosed in one aspect is a voltaic cell assembly comprising one or more voltaic cells, a photovoltaic cell in one embodiment; an elastomeric film and a transparent film, the voltaic cell sandwiched there between. The elastomeric film can be formed from a natural rubber or an isobutylene-based elastomer. More particularly, the elastomeric film may comprise a DVA of a polyamide and a functionalized poly(isobutylene-co-p-methylstyrene). The assembly described is useful for a number of end use articles including roofing shingles, automotive components, building components, and, in general, solar arrays.
