摘要

本文提出了一种利用单电流-电压曲线提取光伏电池模型参数的简单方法。实验结果是在光伏电池照度恒定的情况下得到的。PV电池的模型为单二极管模型,包含5个参数:$\mathbf{I}_{\mathbf{ph}}$为光在PV电池中产生的电流,$\mathbf{I}_{\mathbf{0}}$为二极管的暗饱和电流,n为二极管的理想因数,$\mathbf{R}_{\mathbf{s}}$为串联电阻,$\mathbf{R}_{\mathbf{sh}}$为分流电阻。该方法已应用于单晶硅6英寸光伏电池。为了验证所提出的模型,在Spice仿真中使用了这些参数。

A Simple Method of Modeling the PV Cell from a Single Current-Voltage Curve
In this paper is presented a simple method to extract the parameters of a photovoltaic (PV) cell model using a single current-voltage curve. The experimental results for current-voltage curve are obtained from the constant illumination level of the PV cell. The used model of PV cell is the single-diode model and contained five parameters: $\mathbf{I}_{\mathbf{ph}}$ – the current generated by light in PV cell, $\mathbf{I}_{\mathbf{0}}$ – the dark saturation current of the diode, n – the ideality factor of the diode, $\mathbf{R}_{\mathbf{s}}$ – the series resistance, and $\mathbf{R}_{\mathbf{sh}}$ – the shunt resistance. The proposed method has been applied for a monocrystalline Si 6 inch PV cell. In order to validate the proposed models, the parameters were used in the Spice simulation.
