摘　　要：当前,在太阳能电池仿真领域,普遍采用漂移扩散和等效电路模型相结合的方法预测太阳能电池的性能并提供优化方案.但是,等效电路模型无法精确量化各复合损失对太阳能电池效率的影响,同时由于节点数限制,SPICE等商业软件亦无法对大规模太阳能电池组件进行高效仿真。针对任意太阳能电池组件仿真,该文提出了四参数等效电路模型和基于修正节点法、多维牛顿法的电路仿真算法,并在非线性元件等效、多维牛顿迭代、约束条件等方面进行数值优化,实现了高精度快速仿真。Currently,in the field of solar cell simulation,a combination of drift-diffusion and equivalent circuit models is commonly used to predict solar cell performance and provide optimization solutions.But equivalent circuit models cannot accurately quantify the impact of various recombination losses on solar cell efficiency.Additionally,due to node number limitations,commercial software like SPICE cannot efficiently simulate large-scale solar cell modules.To address the simulation of any solar cell module,this paper proposed a fourparameter equivalent circuit model and a circuit simulation algorithm based on the modified nodal analysis method and the multi-dimensional Newton method.This paper achieved highprecision rapid simulation through numerical optimization in areas such as nonlinear component equivalence,multi-dimensional Newton iteration,and constraint conditions.
