为了克服传统氙灯太阳模拟器成本高、寿命短、功耗大等缺点,提高太阳电池测试的准确性,本文首先设计了一种基于11种波段的LED太阳模拟器,在光谱匹配度、不均匀度和不稳定度上均达到IEC60904-9-2007规定的A级标准。在此基础上,开发了配套的太阳电池测试系统,经过光源控制、数据处理、温度修正以及参数计算,得到太阳电池的电特性参数。实验结果表明,系统可以准确测得单晶硅太阳电池片的各项参数,且结果稳定,从而验证了光源的可靠性及测试方法的科学性。

Development of LED Solar Simulator and Solar Cell Test System

The commonly-used xenon solar simulator has the disadvantage of high cost, short life circle and high power consumption. In order to improve the accuracy of the solar cell test, a multi-wavelength LED solar simulator was designed. The spectral matching, non-uniformity and instability of the irradiance satisfy the class A standard specified in IEC60904-9-2007. Moreover, a corresponding solar cell test syst-em was developed, having the function of light source control, data processing, temperature calibration and parameter calculation. The experiment results showed that the electrical characteristics of monocrystalline sili-con solar cell could be accurately obtained, and the results were stable, comfirming the reliability of the light source and the scientificalness of the test method.
