Abstract
An encapsulant is an important component in PV module that binds silicon solar cell to glass and backsheet layers. In current time, co-extruded EVA-POE-EVA sandwich (EPE) has become next-gen promising material for long term reliability of PV module. In this study, EPE and EPE-down conversion (EPE-DC) are laminated on 3 different makes of solar glasses in Glass-Encapsulant-backsheet configuration to study the adhesion at Encapsulant-Glass interface before and after high accelerated stress test in pressure cooker test chamber. The adhesion strength has been compared with standard EVA result. The results show better performance and % retention of EPE-DC after extreme ageing at 121ºC temperature and 100% RH for 48 hours compared to EPE and standard EVA.
