igh efficiency solar cells are of a wide interest worldwide due to the higher demand on renewable energy resources.
Optimizing the design and fabrication of any type of solar cells is a vital process to minimize any loses due to fabrication
limitations and errors. In this work the effect of the optimization of the annealing process was studied. Two scenarios were
experimentally investigated in the first scenario the substrate temperature was help at elevated temperature than room
temperature without post annealing. In the second scenario a post annealing process was performed by using RTA technique.
As a result, the substrate heating during metal contact deposition by using E-beam evaporation enhanced single junction GaAs
solar cells power conversion efficiency by up to 25% compared to the case of post annealing. This result is obtained by the J-V
characterization of different single junction GaAs solar cells for both annealing processes.
