摘　　要：文章旨在优化径向结PIN结太阳能电池的结构设计,以提高光电转换效率。通过Comsol Multiphysics软件模拟仿真,系统调整了I区厚度(100~300nm)和硅纳米线长度(1100~2100nm),以评估不同参数组合对电池性能的影响。研究结果表明,当I区厚度为200nm、纳米线长度为1300nm时,电池的光电转换效率达到最大值。该径向结构不仅充分发挥了“陷光效应”,在电场分布和载流子扩散方面也表现出显著优势,同时有效解决了光吸收与光生载流子收集的矛盾,降低了暗电流密度,提升了开路电压。研究结果验证了径向结构在光伏应用中的优越性,为未来的实验研究和实际应用提供了理论依据和设计指导。This paper aims to optimize the structural design of radial junction PIN junction solar cells to improve the photoelectric conversion efficiency.Through Comsol Multiphysics software simulation,the system adjusted the thickness of zone I(100~300nm)and the length of silicon nanowires(1100~2100nm)to evaluate the effects of different parameter combinations on the battery performance.The results show that when the thickness of zone I is 200nm and the length of nanowire is 1300nm,the photoelectric conversion efficiency of the battery reaches the maximum.The radial structure not only gives full play to the"trapping effect",but also shows significant advantages in electric field distribution and carrier diffusion.At the same time,the contradiction between light absorption and photo-generated carrier collection is effectively solved,the dark current density is reduced,and the open circuit voltage is increased.The research results verify the advantages of radial structure in photovoltaic applications,and provide theoretical basis and design guidance for future experimental research and practical application.
