摘　　要：基于太阳电池光生电流远大于反向饱和电流、并联电阻远大于串联电阻以及光生电流近似等于负的短路电流3个边界条件,结合太阳电池在短路点、开路点和最大功率点处的极值表述,提出了一种解析求解太阳电池光生电流、反向饱和电流、理想因子、并联电阻和串联电阻5个电性参数的方法,并研究了方法的特点。通过与文献实验数据的对比表明,本文方法不仅具有正确性,而且适用于各种条件下的各种类型电池;通过实验表明,本文方法具有较高的计算精度和速度,误差在2%以下,时间小于0.2s。Based on three boundary conditions that solar cell photocurrent is much larger than the reverse saturation current,the shunt resistance is much larger than the series resistance and photocurrent is ap- proximately equal to the negative short-circuit current, an analytical method for the extraction of solar cell parameters is proposed,and its characteristics are studied in detail. The method combines with the description at the short-circuit, open-circuit and maximum power point of solar cell. The parameters in- clude the solar cells photocurrent, the reverse saturation current, the ideality factor, the shunt resistance and the series resistance. When this method is used to analyze existing literature data,the results do not only certify correctness of the method, but also show that the method can be applied to different kinds of solar cells under various conditions. When the method is applied to the experimental data, the results prove that this method has a high computational accuracy and speed. The experiment and analysis results show that the fitting error is less than 2% and the calculated time is less than 0. 2 s, which meet solar cell parameters extraction accuracy and time requirements in engineering application field. This research enriches the current solar cell parameters extraction method.
