摘　　要：提出一种'改进的开路电压点斜率法'(简称:斜率法)的串联电阻测试方法,并利用Lambert’s W函数显化太阳电池电流电压关系的方式,将'改进的开路电压点斜率法'和其他3种方法下得到的串联电阻值进行比较。通过实验验证了模拟分析的结果,给出了一定的理论解释,并指出当前太阳模拟器测试结果偏大的原因。通过分析得出结论:在这4种方法中,斜率法具有测试方便、结果可靠、不重复度小等特点,是最适合太阳模拟器中串联电阻提取的算法。An improved ＂slope method of the I-V curve at open circuit point＂ （ slope method） for determining the series resistance of solar cells was presented in this paper, and using Lambert＇ s W function to express the current-voltage relationship of solar cells. The slope method was used to compare with three other methods for series resistances. Then, the simulated results were verified by experiment and some theoretical explanations were given. Especially, the reason why the ＂data from current simulator test is large was explained. The analyses results showed that the slope method stands out among those four methods to extract series resistance for the solar simulator with convenient, reliable, and small non-repetitive features.
