Numerical simulation and optimization of high-efficiency GaAs/P-Si and AlGaAs/P-Si based solar cells

Malaysia has a significant biomass, solar and hydro potential under investigation as in request for clean and sustainable energy keep on growing which has led to much research on solar cell technologies. Solar panels, in particular those made from Gallium Arsenide (GaAs) and Aluminium Gallium Arsenide (AlGaAs) materials have demonstrated the conceivable to be more energy effective than traditional silicon based solar cells. The goal of the study is to find a solar cell structure with the highest possible efficacy: a GaAs/p-Si and AlGaAs/p-Si solar cells are simulated using PC1D software. Performance of solar cell was improved by optimizing key parameters including device thickness, doping concentration and Anti-Reflection Coating (ARC) design.
