Structural, Optical and Simulation Studies of Hybrid Perovskite CH۳NH۳PbI۳ Using Al Doped ZnO as an ETL and CuSbS۲ as a HTL for Solar Applications

Researchers have always had a challenge figuring out the discrepancy between solar cell simulation and experimental results. The purpose of this research is to elaborate and examine organic-inorganic perovskite lead methylammonium iodide  as an absorber layer for a solar cell application, and also explore novel structures employing Al doped ZnO as an ETL, CuSbS۲ as HTL through SCAPS ۱D simulator program. The  was prepared employing the sol-gel dip-coating method, a low-cost production process. In order to establish the films' structural integrity, the absorber layer films were analyzed using X-ray diffraction. Ultraviolet-visible (UV-Vis) spectroscopy was utilized to compute the optical parameters, which include the absorption, transmission, and band gap energy, which will be utilized during the simulation part. An optimization investigation involving the influence of CuSbS۲, perovskite, AZO thicknesses, defect density of the absorber layer, and different operating temperatures on the electrical output parameters (Voc, Jsc, FF, and ƞ) revealed an improvement in the efficiency of solar cells to ۲۵.۳۱% under ۰.۹ µm, ۰.۷ µm, and ۰.۰۴ µm thicknesses for the hole-transporting material, absorber, and electron-transporting layer, respectively. The AZO/perovskite and the perovskite/HTL interfaces were also examined. The series and shunt resistance were simulated at different values to investigate their effect on the device’s works.
