摘　　要：通过分析太阳电池I-V特性的实验室测试方法,研究一种适用于稳态光源下的双通道I-V特性测试方法,在原有单通道四线制测试方法的基础上增加另一个通道,用于参考电池的同步测试,在太阳电池进行I-V测试后,通过逐点修正的方法对测试数据进行处理,得出更为准确的I-V曲线。该方法可以有效减少稳态光源的不稳定性对测试造成的影响,提高测试系统的准确度和重复性。A solar cell dual-channel test method based on steady light source by analyzing the solar cell I-V characteristic laboratorial test method was proposed. On the basis of the original single channel four wire test method, another channel was added to use for reference cell synchronism test in this method. After test, the more accurate I-V curve was got through point by point correction method to deal with test data. The results show that this test method can effectively reduce the effects of steady light source instability of the test. The accuracy and repeatability of the test system were increased.
