Abstract

Background and Objectives: Solar cell is an electronic device which harvest photovoltaic effect and transform light energy to electricity. An efficient double junction InGaN/CIGS solar cell can be simulated using Silvaco ATLAS software. In this study, a thin CdS top cover layer is used as the anti-reflector layer.
Methods: To reach the current matching condition, changing the thickness of this CdS layer, we can enhance the short-circuit currents of both the top and bottom cells. To gain a desired efficiency, different design parameters, such as the doping concentrations and the thicknesses of the various layers of the cell are optimized. This cell is designed to be used in a real environmental situation. Results: By using the appropriate parameters, and under matching conditions, the efficiency is optimized as well as the filling factor is increased. Considering the proposed structure and the simulation results, an optimum efficiency of 41.87% is achieved and also the obtained fill factor is equal to 75.16%.
Conclusion: In this paper, a new structure for an efficient double junction InGaN/CIGS solar cell, was proposed. In our proposed structure, a thin CdS layer is used as the anti-reflector layer. To get a desired efficiency, different design parameters, such as the doping concentrations and the thicknesses of various layers of the cells were optimized.
