Abstract :

Since extremely inexpensive manufacturing costs, exceptional light intensity collecting capabilities, and high efficiency, organic perovskites have garnered significant interest in the area of solar cells in recent years, making them more desirable than other existing solar cell materials. The findings indicated that the performance of lead-free perovskite solar cells was less adversely affected by elevated temperatures compared to lead-based solar cells, such as those utilizing lead perovskite CH3NH3PbBr3. Lead-free perovskite solar cells have recently attained efficiency of around 18.23 percent. The conventional configuration of a perovskite-based planar heterogeneous solar cell comprises an electrode, a hole transport material (HTM), a perovskite absorber, an electron transport material (ETM), and a front electrode. This research presents ETM (ZnO) combined with perovskite Cs2AgBi0.75Sb0.25 and Spiro-OMeTAD as the hole transport material (HTM) in an inorganic perovskite solar cell, achieving a high efficiency of 18.23% using SCAPS modeling.We investigate the impact of Cs2AgBi0.75Sb0.25 layer thickness, varying from 0.1µm to 1µm, with optimal results seen at 0.1µm.
