This study investigates the performance optimization of III-V/Si bifacial tandem photovoltaic (PV) modules integrated with dynamic tracking systems. To address the limitations of conventional PV technologies under varying environmental conditions, we propose a solution that combines high-efficiency tandem architecture with bifaciality and tracking to enhance energy capture from both direct and reflected irradiance. The research employs simulation models validated using environmental datasets including global horizontal irradiance (GHI), ambient temperature, and surface albedo. Simulation results reveal a peak output of 109.2 W, a combined efficiency of 29.14 %, and up to 8.81 kWh/m2 daily yield with east–west tracking, driven by a bifaciality factor of 0.80 and a 30–40 % gain from tracking. The study highlights the significant impact of irradiance and geographic factors on PV performance and demonstrates the superior output of bifacial tandem modules across diverse locations. Future work will focus on experimental validation and optimization of system configurations for scalable deployment in real-world scenarios. © 2025 Elsevier Ltd
