Numerical simulation of various structures of a solar cell plays a crucial role in the design, performance prediction and the comprehension of the physics involved in their operation. It also allows of better understanding the different ways to improve the solar cells efficiency before the manufacture of the practical cell. Objectives: In this study, numerical results were obtained using SCAPS-1D program in order to improve GaAs solar cells performance. Methods: The analysis deals with the role of Alx Ga1-x As-type window layer on overall electrical performance of solar cells. The variations of thickness and doping levels in this window layer were also investigated. Findings: By growing this layer at the GaAs surface, the efficiency increased from 17.23% to 27.37%. The simulation results showed that this window layer should be very thin and slightly doped to achieve good performances of the entire solar cells. Improvements/Applications: These results are interesting because they show how much the window layer is important in improving the efficiency of GaAs solar cells.
