Evaluation of the Effect of Backsheet Properties on PV Encapsulant Degradation under Ultraviolet-Damp-Heat Conditions

Djamel Eddine Mansour

The reliability of photovoltaic (PV) modules is highly determined by the durability of the polymeric components (backsheet and encapsulant). The power degradation and failure of PV modules can be caused by changes in the physical, chemical, and mechanical ...
