Performance Enhancement in Silicon Solar Cells: A Systematic Analysis of MgF2, SiO2, and TiO2 Coatings

Abstract

The conversion of power efficiency, or PCE, is the main metric used to evaluate the performance characteristics of solar cells. The anti-reflective coating (ARC) increases the power conversion efficiency (PCE) of solar cells by preventing light loss on their surface. This study investigates the different materials applied as double-layer anti-reflective coatings (DLARC) on crystalline silicon (c-Si) solar cells. The complete procedural process for silicon solar cell simulation was performed using PV Lighthouse's Wafer Ray Tracer application. Examined were five light trapping (LT) methods with various kinds of double layers. In comparison to the reference c-Si (without ARC), the highest potential photocurrent density (Jmax) of c-Si with ARC shows an improvement. At 42.20 mA/cm2, SiO2/TiO2 yields the highest value of Jmax in LT S II. Structure II's Jmax improvement was the highest, at 10.01%. According to this finding, DLARC may be utilized to reduce optical loss and raise solar cell efficiency.
