作为对聚光特性的补偿,对电池进行暗特性测试,从曲线中提取了几个重要的电学特性参数.搭建了一套CPV测试系统,分析了GaAs电池500倍聚光条件下的输出特性,测得模块的峰值效率为22.24%,峰值功率为23.56 W,短路电流温度系数为1.9 mA/℃,开路电压温度系数为-5.9 mV/℃.户外特性测试为光伏发电系统提供可靠性,更多的实验表明,效率和填充因子在一天内的变化趋势相反,最值均在光通量下降为最大值时的90%左右出现.实验表明,Isc(短路电流)和Voc(开路电压)随光照强度的变化与理论分析一致.

Dark I-V test Was tested as compensation for light I-V characteristic.and it provided several important electrical parameters.After a CPV test system was setup,a peak efficiency of 22.24% and a peak power of 23.56 W were achieved in this module designed for a 500 times geometric concentration ratio.The short-current temperature coefficient is 1.9 mA/℃ and the open-voltage temperature coefficient is -5.9 mV/℃.The measurement of outdoor characteristics provides evidence of reliability for solar PV system.The additional experiments suggest that the efficiency and fill factor have the opposite trend in one day.When the irradiance drops to about 90% of its peak value,efficiency has maximum value and fill factor has minimum value.Isc and Voc change with light intensity,which is in consistent with theoretical analysis.
