Designed and Simulation of AlGaAs: GaAs Thin Film Solar Cell Using PC1D Program

Abstract

Obtained the highest competence and finding the best combination of thickness and concentricity of multilayer solar cells is one the most prominent problems in the field of photovoltaic energy. In this research AlGaAs/GaAs solar cell with four layers of window layer, emitter layer, absorber layer and back surface layer. Is modeled in PC1D emulation software. The performance of the solar cell was studied by changeful the thickness and doping concentration of the window layer from the range (0-1)μm, (1015-1020) respectively. Where the best efficiency was 31.2% at thickness and doping 1015cm-3. Where changing the thickness and doping concentricity of the absorber layer from the range (0-5)μm, (1015-1020) respectively. The highest efficiency was 31.4581% at thickness 3.67μm and doping is 1015cm-3. The results of the final solar cell parameters were Isc, Voc, F.F and η has been observed as 31.8mA, 1.109 V, 89.32% and 31.4581% respectively.
