摘      要：Gallium arsenide (GaAs)-based photovoltaic (PV) cells are widely recognized for their outstanding efficiency and excellent light absorption capabilities, making them a preferred option in advanced solar energy technologies. Despite these advantages, their widespread application is limited by high production costs, thermal management issues, and inefficient charge carrier transport. This study aims to overcome these challenges by developing and optimizing a multilayer solar cell with the configuration Al/ZnO/CdS/GaAs/NiO/Au using SCAPS-1D simulation software. Key parameters, such as layer thickness, donor and acceptor densities, series and shunt resistances, and operating temperature, were systematically optimized to boost the device s performance. Under standard AM1.5 G illumination, the optimized solar cell achieved an open-circuit voltage (V OC ) of 1.0825 V, a short-circuit current density (J SC ) of 31.42 mA/cm², a fill factor (FF) of 87.43 %, and a power conversion efficiency (PCE) of 29.74 %, with quantum efficiency (QE) nearing 100 % within the visible spectrum. These enhancements demonstrate not only the potential for achieving high efficiency but also practical strategies for addressing key limitations in GaAs PV technology. The study highlights the promise of these optimized cells for high-performance applications, including space PVs, concentrated solar power systems, and other scenarios requiring compact and efficient energy solutions.
