Simulation of CZTSSe thin film solar cell, comparison, optimization and investigation of the effect of temperature on efficiency

The amount of energy use is increasing day by day with the increase in population and industrialization. One of the renewable sources that does not have any harmful effects on the environment and human health is solar energy. A clean and cheap source that can easily provide many human needs for energy. Thin film solar cells are made of several very thin layers deposited on top of each other. The advantages of thin film solar cells compared to crystal solar cells are flexibility, light weight and simple integration. Cu(In,Ga)Se۲ (CIGSe) sun based cells have accomplished exceptional efficiencies surpassing ۲۰%. Be that as it may, components such as indium and tellurium are uncommon, and cadmium is very harmful, which may constrain the usage of these gadgets at the terawatt scale. In later a long time, Cu۲ZnSnS۴ (CZTS), Cu۲ZnSnSe۴ (CZTSe), and Cu۲ZnSn(S,Se)۴ (CZTSSe) have developed as substitution materials for thin-film PV due to promising optoelectronic properties and the utilize of nontoxic, earth-abundant components. In this article, we simulated CZTSSe solar cell with Al-ZnO/ZrS۲/CZTSSe/Mo structure using SCAPS-۱D software and compared CZTSSe absorber layer with CZTS and CZTSe structures. Next, we optimized the absorber layer to obtain the best performance of the solar cell by changing the thickness of this layer. In the end, we showed the effect of ambient temperature on the efficiency of the optimized solar cell.
