摘　　要：基于太阳电池相关文献参数,对比研究并分析太阳电池单指数二极管电流输出方程与8种工程数学模型之间的绝对误差及均方根误差。结果表明,8种工程数学模型总体上均能正确重现太阳电池性能,但均存在绝对误差随电压的增大而增大的现象;原因是工程模型无法描述电池非线性特性随着电压增大而显著增强的现象。此外,发现尽管不同假设条件下8种工程数学模型对各类太阳电池性能的重现存在适用范围,但在帕德逼近下建立的多项式形式模型误差最小,原因在于帕德逼近下的展开最能逼近e指数特征。In this study, we analyze absolute error and root-mean-square error between single-diode equation and eight kinds of engineering mathematical models of the photovoltaic cells based on literature data. The results show the eight engineering mathematical models can accurately reproduce performance of the photovoltaic cells. However, the absolute error value increases with the bias voltage. The reason is that the engineering models are unable to describe the dramatic nonlinear effects of solar cell. Although eight kinds of engineering mathematical model can＇ t applied to all kinds of photovoltaic cells under the same precision, the model error of polynomial form under pade approximation is minimum. The reason is that pade approximation can best close to the e index.
