Optimization of Absorber Layer and Operating Temperature of Copper Indium Gallium Selenide Solar Cells Using Different Metal Contacts

Device simulation was employed to investigate the effect of metal back contact electrodes on performance n-type CdS/p-CIGS thin film solar cells using varying thicknesses absorber layer at operating temperature 300K. The working temperatures also studied from 300K 400K in steps 10K. simulations were carried out standard cell capacitance simulator (SCAPS) 3.3.03 version software. results showed better efficiencies optimized thickness 3µm for all under study. maximum 17.5 %, 15.5 11.5 3.5 % and 3 estimated CIGS 300 K platinum, gold, cobalt, silver copper respectively. efficiency decreases as increases 400 K. It is recommended that µm appropriate efficient cost effective economic reasons.
