EVA browning and the time-dependence of I-V curve parameters on PV modules with and without mirror-enhancement in a desert environment
Two independent experiments are described that were performed on samples of EVA-laminated photovoltaic modules which form part of a grid-connected PV system in the Negev desert. Both types ofExpand
