Summary

Important physical properties of materials used in PV module packaging are presented. High-moisture-barrier, high-resistivity, adhesion-promoting coatings on polyethyl-ene terephthalate (PET) films have been fabricated and characterized for use in PV module application and com-pared to standard polymer backsheet materials. Ethylene vinyl acetate (EVA) and an encapsulant replacement for EVA are studied for their water vapor transmission rate (WVTR) and adhesion properties. WVTR, at test conditions up to 85C/100% relative humidity (RH), and adhesion val-ues are measured before and after filtered xenon arc lamp ultraviolet (UV) exposure and damp heat exposure at 85C/85% RH. Water ingress is quantified by weight gain and embedded humidity sensors.
