A critical failure mechanism for PV modules is the degradation in performance as a result of exposure to temperature and humidity. In the case of flexible PV modules, moisture-induced damage becomes a greater concern, since the moisture resistance of barriers and polymer packaging is expected to be lower than that for conventional glass–glass PV products. The work presented here is aimed at establishing, through the use of accelerated testing, the field lifetime of flexible PV modules with regard to moisture-induced degradation.
