Abstract: 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 currentvoltage 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.
