Conducting a computational study for the design of CFTS solar cell with high efficiency using the AFORS-HET program

In this work (paper), the solar cell CFTS/CdS/ ZnO/AZO characteristics were simulated using Cu2FeSnS4 compound as an absorption layer. Optical absorption studies reveal that Cu2FeSnS4 has an energy gap of (1.32-1.5) eV, which indicates that these compound nanoparticles are absorbent materials that can be used to manufacture photovoltaic cells. The effect of the thickness and concentration of Cu2FeSnS4 layer was studied on the solar cell performance using the one-dimensional AFORS-HET simulation program. The results showed an increase in The cell efficiency from 0.07% to 10.94%, the value of the short circuit current was about 30.83 A=cm(2) and the open-circuit voltage was 0.697 V after the optimization of the solar cell.
