Computational study of CuAlO2/ZnO, and NiO/ZnO Perovskite Solar Cells by Numerical Simulation

This study presents a comparative analysis of the performance of CuAlO2/ZnO and NiO/ZnO perovskite solar cells employs numerical simulation with an emphasis on temperature flactuations, layer thicknesses and electrical propeties using the SCAPS-1D modlling tool, the photovoltaic parameters such as open circuit voltage (VOC), short circuit current density (JSC), fill factor (FF), and power convrsion efficiency (PCE) were invstigated under standard test conditions and varying operational senarios. The effects of the hole transport layer (HTL) materials (CuAlO2 and NiO) on device performace were assessed with particular attention to their band alighment, carrier mobility, and defect density. Results indicate that CuAlO2 structure achieves higher efficiency due to better band alghment and charge transport properties compared to NiO/ZnO. However, the NiO-based device demostrated superior thermal stability over a wide temperature range. Optimization of HTL thickness and defect density further enhaned device performance with CuAlO2 exhibiting optimal peformance at lower defects densities. This comparative study provides an insights into material selection an design parameters for efficient and stable perovskite solar cells
