Abstract

This paper indicated a numerical modeling of ultra thin copper indium gallium diselenide (CIGS) solar cells. An optimum value of the thickness of the structure has been calculated and it is shown that by optimizing the thickness of the cell, efficiency has been increased and cost of production can been reduced. Numerical optimizations have been done by adjusting parameters such as thickness of the layers and the gap. It shows that by optimization of the considered structure, open circuit voltage (Vco) increases and an improvement of conversion efficiency has been observed in comparison to the conventional CIGS system.
 
Key words: Graded pseudo copper indium gallium diselenide (CIGS)-Zn(O,S), solar cells, efficiency enhancement, solar capacitance simulator (SCAPS).
