Abstract
A study of leakage currents in PV modules has been shown to be effective in early detection of design, material or process flaws in PV modules. Corrosion has been found to occur in some a-Si:H PV modules during accelerated testing under damp-heat with high voltage bias conditions. The objective of this project is to carry out accelerated testing of PV modules deployed in hot and humid climate under very high voltage bias conditions so as to understand correlation, if any, between the leakage current and mobile corrosive impurities. Moreover, efforts will be made to elucidate the modes and mechanisms of failures in PV modules with an aim to apply the Physics of Failure methodology for improving the service lifetime of PV modules specially developed for high voltage PV systems.
