提出一种在Matlab/GUI环境下设计的晶体硅太阳电池数值模拟软件.通过光生少数载流子连续性方程建立了单晶硅N+/P/P+结构太阳电池的物理模型。通过引进有效迁移率和有效少子扩散长度概念.并考虑多晶硅中晶界复合后,实现了对单晶硅、柱状多晶硅太阳电池的开路电压、短路电流、填充因子、转化效率、串并联电阻等电池性能的参数指标的数值模拟。程序模拟结果通过数值和图形两种方式输出.模拟结果与实验结果接近,能够为晶体硅太阳电池的设计与制备起到较好的指导作用。本程序对于以N型材料为衬底的晶体硅太阳电池同样适用。
A software for the numerical simulation of crystalline silicon solar cells is developed. Photocarrier continuity equation, effective mobility, effective minority carrier diffusion length and carrier recombination on crystal boundary of muhicrystalline silicon are taken into account in the physical model. The software outputs the numerical simulation of crystalline silicon solar cells by numerical results and graphics. As the simulation results close to experimental data, the software can be a good guide for the design and production of crystalline silicon solar cells.
