Abstract

This research aims to improve the performance of silicon solar cells by using double-layer anti-reflective coatings (DLARCs). The goal of this research is to investigate how DLARCs minimize the reflection of light and maximize energy output. The DLARCs are simulated, using software known as PC1D, by creating three DLARC configurations: MgF₂/TiO₂, SiO₂/TiO₂, and Al₂O₃/TiO₂. The performance of all the configurations was found to be higher than that of the reference cell. The MgF₂/TiO₂ coating had the best efficiency of 23.10%, while the reference cell had an efficiency of 15.70%. The comparable performance of MgF₂/TiO₂ and SiO₂/TiO₂ can be attributed to their proximity in refractive indices, as well as to the limitations of the used material database in the simulation.
