Popis:	36th European Photovoltaic Solar Energy Conference and Exhibition; 1200-1203 This paper investigates how lamination temperature effects the various properties of most commonly used ethylene vinyl acetate (EVA), which are important for photovoltaic module performance and reliability. EVA sheets with 28% vinyl acetate (VA) and 33% VA are cured at different temperatures between 130 °C and 160 °C for 8 minutes. Here we have investigated the effect of curing temperature on gel content, transmittance, resistivity, adhesion strength, and thermal decomposition of EVA. Maintaining these properties in the acceptable range is important for long term durability of the modules. This comprehensive analysis helps in finding the best temperature window for a given lamination time setting.
