Performance Analysis of BiCoRE Solar Cells under Variable Albedo Conditions

This investigation examines the performance of BiCoRE (Bifacial Co-diffused Rear Emitter) solar cells under varying albedo conditions, focusing on critical performance parameters, namely short-circuit current density (Jsc), open-circuit voltage (Voc), fill factor (FF), and output power (Pout). Using Personal Computer 3D (PC3D) software for detailed 3D modeling and dual-surface illumination simulations, we observed significant performance improvements under reflective surface conditions. For instance, on snow-covered surfaces, the output power increased from 20.69 mW/cm² to 34.41 mW/cm², marking a 66.31% improvement compared to front-side-only illumination. The investigation further models the relationship between albedo variations and the four key performance parameters of the BiCoRE cell. The resulting linear models demonstrate a robust correlation, enabling accurate predictions of cell performance across diverse albedo levels without the need for additional simulations. Comparisons between the linear models and the simulation results confirm strong alignment across all parameters. High albedo values, particularly in reflective environments, substantially boost energy output, emphasizing the importance of albedo as a pivotal factor for optimizing the energy efficiency of BiCoRE solar cells. These results highlight the potential of bifacial designs to enhance energy capture in a wide range of environmental scenarios.
