- Abstract
The inevitable energy demands in today’s world have shifted the interest of many researchers toward one of the fastest growing technologies, perovskite solar cells (PSCs). Because of its esteemed performance, high absorbance, and cost-effective fabrication as compared to the existing methodologies, PSCs are eminently preferred. In this study, logical device simulation of the mixed halide with chlorine as a derivative halide (CH3NH3PbI3−XClX), an absorber layer, is characterized by bandgaps, absorption coefficient, thickness, doping concentration, etc. With the need for a highly efficient solar cell, a deliberate choice of its constituting materials is also a challenging job. Performance of a mixed halide perovskite solar cell (PSC) using copper iodide (CuI) as a hole transport material (HTM) boosts the device performance. Simulation results of the optimized design show high proficiency to the existing model as the power conversion efficiency (PCE) and fill factor (FF) is increased by 3.42% and 4.85%, respectively, at an increased short-circuit current density (JSC) and a comparable open-circuit voltage (VOC). The result also shows compatibility between alloy material as an electron transport material and an inorganic HTM.
