Abstract :
Thin Film Solar Cell is a technology which has a great potential as it has low material consumption and relatively high efficiency to others. Among thin film solar cells CIGS is a promising one. But due to scarcity of gallium and indium its industrial production can be affected. Here in this paper via simulation (using device simulator) we have tried to achieve good acceptable efficiency using very thin layer of CIGS absorber layer with the help of grading and appropriate gallium composition and by optimizing emitter efficiency which is close to the efficiency of CIGS cells having thick absorber layer.
