Encapsulant material is an important component of the Photovoltaic (PV) modules. Generally Ethylene Vinyl Acetate (EVA) is used as the encapsulant material in PV modules due to its low lost and other properties like high adhesion to different module materials, high volume resistivity, high optical transparency and adequate mechanical strength to accommodate stresses induced by thermal expansion of glass and solar cells. The purpose of this investigation is to compare two different grades of virgin EVA films by various techniques like Fourier-transform infrared spectroscopy (FTIR), Raman spectroscopy, Thermal gravimetric analysis (TGA), UV-Vis spectroscopy and Broad band dielectric spectrometry.
