Abstract :
The results of reflection and transmission calculations for heteroface AlGaAs-GaAs solar cells are presented. Effects of single and double layer AR coating are included in a matrix formulation analysis. Due to reflection losses the only transmitted light is about 66.415% of the AMO spectrum. By applying a double antireflection coating with optimum thicknesses, this transmission can be increased to around 87% for Al0.8Ga0.2As taking into account the grid shadow and window layer effect on the optical properties (reflection and transmission)
