摘要

Antimony selenide (Sb2Se3) exhibits promising characteristics as an absorber material in photovoltaic solar cells. To enhance the efficiency of Sb2Se3 solar cells, we propose a reevaluation of the device design through the utilization of device simulation techniques and optimization algorithms. To ensure the model's accuracy, a calibration procedure is performed by comparing the experimental data obtained from a fabricated structure (Mo/MoSe2/Sb2Se3/TiO2/CdS/ZnO/Al:ZnO) with numerical simulation results. Simultaneous investigation was conducted to assess the efficacy of incorporating sulfur into the absorber layer of Sb2Se3 and introducing zinc into the CdS buffer layer within the conventional Sb2Se3 cell configuration. In this study, we examined the influence of alterations in energy levels at the Cd1-xZnxS/Sb2(S1-ySey)3 junction. Our research demonstrates that by utilizing an Sb2(S1-ySey)3 absorber layer with a Se concentration of 0.8 and a Cd1-xZnxS buffer with a Zn mole fraction of 0.7, the cell efficiency can be enhanced from 9.2% to 15.6%. The presented solar cell undergoes optimization of crucial design factors, comprising the thickness of the buffer and absorber layers, as well as their doping concentration. These optimizations are achieved through the utilization of the grey wolf optimization algorithm and fuzzy system, for the first time. By meticulously adjusting each of the aforementioned key design parameters, we were able to achieve an impressive efficiency of approximately 18% for the suggested Sb2(S0 & sdot;2Se0.8)3/Cd0 & sdot;3Zn0 & sdot;7S cell.
