Abstract :

Numerical modeling of polycrystalline thin-film solar cell serves as an imperative procedure to test the suitability of proposed physical clarification and to anticipate the effect of physical changes on cell performance. All in all, this must be conducted with only partial knowledge of input parameters. In this paper, we evaluated the numerical simulation of CdS/CIGS tandem multi junction solar cells by applying the AMPS-1D software aiming at finding the optimum design of the new multi-junction tandem solar cell preparing the ground for its most efficient operation. We studied the effect of CIGS p-layer thickness on the output parameters of the CdS/CIGS tandem multi junction solar cells, such as the density of short-circuit current, open circuit voltage, fill factor and efficiency. By applying the results of the numerical simulation, it was concluded that the maximum efficiency of this solar cell was equal to 48.3%, which could be obtained with the CIGS p-layer thickness of 600 nm at a standard illumination of AM 1.5.
