This study investigates the performance and efficiency of a perovskite solar cell through numerical simulation. The main objective is to evaluate the electrical characteristics of the device and to determine the key parameters affecting its photovoltaic efficiency. A perovskite-based solar cell structure was modeled by defining the electrical and optical properties of the absorber layer, electron transport layer, hole transport layer, and contact materials. The effects of selected device parameters, including absorber layer thickness, defect density, carrier concentration, and material properties, were analyzed systematically. The performance of the simulated solar cell was evaluated in terms of open-circuit voltage (Voc), short-circuit current density (Jsc), fill factor (FF), and power conversion efficiency (PCE). The simulation results demonstrate that the optimization of layer properties and device parameters has a significant influence on overall cell performance. In particular, appropriate control of the absorber layer and charge transport characteristics contributes to reduced recombination losses and improved charge collection. The findings indicate that numerical simulation provides an effective approach for predicting the behavior of perovskite solar cells and identifying suitable design parameters before experimental fabrication. This study therefore contributes to the optimization of perovskite photovoltaic devices and supports the development of high-efficiency, cost-effective solar energy technologies.
