The increasing demand for renewable energy sources has high-lighted the importance of optimizing photovoltaic cell technologies. Hetero-junction (HJT) silicon photovoltaic (PV) cells are recognized for their high efficiency, but the challenges remain in maximizing their performance through structural optimization. The efficiency of HJT cells is often hindered by issues related to charge carrier recombination and suboptimal electric field distribution, necessitating innovative solutions to overcome these limitations. This study investigates the optimization and enhancement of HJT silicon PV cells by varying their structural geometries. The primary geometries analyzed include planar, columnar, and pyramid configurations, each with different variations. Using Silvaco TCAD Simulator software, the research focuses on optimizing the electric field distribution, hole density, and charge carrier concentrations to improve the overall performance of HJT PV cells. The findings reveal that the planar geometry with an N-type top region achieves the highest efficiency of 16.5247%, due to its uniform electric field distribution and effective charge separation. The pyramid geometry also shows significant potential due to its enhanced light trapping capabilities, while the columnar geometry, despite its innovative design, requires further optimization. This study provides valuable insights into the effects of geometric modifications on the essential characteristics of HJT cells and offers recommendations for future research to further enhance photovoltaic cell performance.
