Abstract

Systematic investigation of aging mechanisms of a glass-clear PVB film interface at the edge of thin film silicon photovoltaic modules has been performed. The modules under study were composed of a front superstrate laminated to a back glass. Different degradation mechanisms responsible for adhesive strengths loss between PVB film and superstrate are discussed. Glass-foil adhesive strength in compressive shear configuration using different glass compositions and module configurations is given. As accelerated aging stress of the modules, standard damp heat test conditions (85° C, 85% relative humidity) have been applied. A chemical analysis of the glass foil interface was performed and the correlation of those results to those coming from wet leakage measurements is also given.
