Numerical Simulation for Optimal Thickness Combination of CdS/ZnS Dual Buffer Layer CuInGaSe2 Solar Cell Using SCAPS 1D


Background/objectives: The usage of Cadmium makes the solar cell very harmful to nature. In order to reduce the usage of Cadmium content in the dual buffer layered Copper-Indium-Gallium-Selenide (CIGS) solar cell, the buffer layer material properties could be tuned. Methods: The current-voltage behaviour of the CIGS solar cell is investigated on the effect of the buffer layer thickness combination by a numerical simulation using SCAPS 1D. Findings: The results indicate that the simulated model with a dual buffer layer shows higher efficiency compared to the individual CdS and ZnS single buffer layered solar cells. Applications: It is also found that 10 nm CdS in combination with 50 nm ZnS provides a maximum conversion efficiency of 25.149%.
