Numerical Thickness Optimization Study of CIGS Based Solar Cells with SCAPS- 1D

The photovoltaic market knew a strong grow in the last few years. Although various sectors and technologies splits the market, the cells containing Silicon dominates it with more than 85%, this is due primarily to the maturity of the nanoelectronic industry which uses massively the Silicon and good performance of the cells [1]. However, the many steps of production make this material technology expensive and reedy, which justifies the interest to develop the cells in less expensive thin layers. Chalcopyrite Cu(In,Ga)Se (CIGS) is a very promising material for thin film photovoltaics and offers a number of interesting advantages compared to the bulk silicon devices.
