Optimization of Efficient Copper-Indium-Gallium Di-Selenide Solar Cell

The current impact reports on the implementation of Copper Indium Gallium Selenide (CIGS) based solar cells have been simulated through software. A novel model FTO/ZnSe/CIGS/Mo/Substrate has been proposed by using a GPVDM simulator. In this investigation, the main focus is to analyze low cost material and optimize it for better efficiency as compare to conventional CIGS solar cells. We observed in our findings that as the thickness of CIGS medium increases, the power conversion efficiency affectively increases. Also, different material testing was also formed for windows and buffer layer, where it has been observed that efficient model must have window layer Fluorine tin oxide (FTO) and buffer layer is Zinc selenide (ZnSe) with thickness of 30nm and 20nm, respectively. Moreover, solar cell with these topographies gives conversion efficiency of 18.51%.
