太阳能电池等效电路模型与仿真算法
Equivalent circuit model and simulation algorithm for solar cells
摘要
Abstract
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 four-parameter equivalent circuit model and a circuit simulation algorithm based on the modified nodal analysis method and the multi-dimensional Newton method.This paper achieved high-precision rapid simulation through numerical optimization in areas such as nonlinear component equivalence,multi-dimensional Newton iteration,and constraint conditions.关键词
