Researchers are becoming more interested in novel barium-nitride-chloride (Ba 3 NCl 3 ) hybrid perovskite solar cells (HPSCs) due to their remarkable semiconductor properties. An electron transport layer (ETL) built from TiO 2 and a hole transport layer (HTL) made of CuI have been studied in Ba 3 NCl 3 -based single junction photovoltaic cells in a variety of variations. Through extensive numerical analysis using SCAPS-1D simulation software, we investigated elements such as layer thickness, defect density, doping concentration, interface defect density, carrier concentration, generation, recombination, temperature, series and shunt resistance, open circuit voltage ( V OC ), short circuit current ( J SC ), fill factor (FF), and power conversion efficiency (PCE). The study found that the HTL CuI design reached the highest PCE at 30.47% with a V OC of 1.0649 V, a J SC of 38.2609 mA cm -2 , and an FF of 74.78%. These findings offer useful data and a practical plan for producing inexpensive, Ba 3 NCl 3 -based thin-film solar cells.
