Abstract

EVA as an encapsulant material is exposed to various UV irradiation, thermal cycles, and humidity conditions. Degradation of EVA can reduce not only power generation due to yellowing, but also a structural integrity of a PV module. In order to investigate degradation mechanisms of EVA in the PV modules, interlaboratory collaborations have been recently started, and the current study focuses on spectroscopic analyses of EVA samples after 180 days cumulative exposure.
