NImpact of Desert Conditions on the Microstructural and Structural Proprieties of Ethylene -Vinyl Acetate (EVA) in Solar Energy

Abstract

This comprehensive study delves into the degradation of Ethylene-Vinyl Acetate (EVA) in solar panels under arid, desert conditions. Employing techniques like Scanning Electron Microscopy (SEM), Fourier Transform Infrared (FT-IR) Spectroscopy, and X-Ray Diffraction (XRD), we observed a marked increase in crystallization within EVA layers, with rates of 46% above and 36% below the cells, surpassing the usual range of 25-33%. SEM analysis revealed significant carbonaceous particle deposition and crevassing in the sun-exposed EVA layer, impacting the efficiency of light transmission to the photovoltaic cells. Moreover, XRD and FTIR analyses detected the formation of novel compounds such as NH₄⁺ and Si-O, indicating complex chemical changes. These findings highlight the need for materials better suited to withstand harsh desert environments, crucial for improving the durability and efficiency of solar panels in such challenging conditions.
