We investigated the effect of changes in the thickness of the absorbing layer and the acceptor concentration on this cell. Meanwhile, we also optimized the bandgap width of CZTSSe and the thickness of PbS. Moreover, an effective method has been applied in the aim of boosting the conversion efficiency, by adding a BSF (back surface field) layer in the cell. The BSF layer helps to enhance optical behavior and reduces recombination losses, consequently reducing the Voc (open circuit voltage) deficit. With the highest conversion efficiency calculated in the simulation, a cell conversion efficiency of 27.70% can be achieved, which is significantly higher than the basic structure, and provides a large electrical power as well as a more optimal filling factor at the same time.
