Highly Efficient CIGS -Based Solar Cell With Different Back Contact Materials Using SCAPS 1-D Framework

Copper Indium Gallium Selenide (CIGS) is a thin-film solar cells that have emerged as a promising technology for cost-effective and efficient photovoltaic cells. To increase the efficiency of CIGS solar cells, integration of back contact with different materials was investigated utilizing Simulator SCAPS-1D and achieved an efficiency of 26.03%. The various factors of solar cell namely efficiency, fill factor, open circuit voltage, short circuit current has been calibrated and compared with the existing experimental results. The impact of defect density, thickness, shunt and series resistance have considered for optimization of solar power cell device with different back contact materials. The impact of temperature on performance of device will be inspected. Output of this work predicts to give an efficient solar cell based on CIGS material using a suitable back contact material.
