Abstract

The purpose of EVA sheet in PV module is to bond or laminate the multiple layers of a module. We studied the influence of EVA sheet gel content on photovoltaic module durability. Gel Content was measured by manufacturing Glass/EVA Sheet/Back Sheet scheme at several curing temperature. Through this experiment, we could confirm that there are changes on Gel Content of EVA Sheet. The transmittance of $140^{\circ}C$/4min process condition was more excellent than the other condition at ultraviolet wavelength range. The thermal stability of $150^{\circ}C$/4min process condition was higher than the other condition.
