连续氙灯发光光谱的设计与应用研究

对太阳实际光谱与连续氙灯的光谱进行了测试，结果显示氙灯发光光谱的红外部分占全部光谱的55.6%，与实际太阳光谱的28.4%有较大差别。依据这种差别进行光谱曲线拟合，得到925 nm最低点的透过率曲线。采用滤光片对氙灯发光光谱的红外部分光强进行适当过滤，测得过滤后的光谱达到标准匹配度。通过测试滤光后6个不同位置点的光谱发现，光谱最大偏差仅为12.5%，表明过滤后的氙灯光谱均匀性较好。利用电致发光检测有缺陷的硅电池进行电池的电性能测试，发现经过采用滤光片和未采用滤光片的连续氙灯光照测试的Ⅰ-Ⅴ电性能值不同，功率相差0.22 W，表明氙灯光谱匹配度直接影响电池电性能测试的准确度。

Luminescent Spectra Design and Application Research on Continuous Xenon Lamp

The continuous xenon lamp spectra and realistic sunlight spectra were compared. The results show that the infrared part of xenon luminescence spectra covers about 57.4% of the total spectra, but the infrared part only covers 28.3% in the standard spectra. According to the difference of the spectra, curve was fitted and λ₀=925 nm of the lowest point of transmittance curve was got. The infrared part of luminescence spectra of xenon was properly filtered by optical filter and the spectra are up to standard marched-degree after filtering. The biggest deviation value for spectra is only 12.5% by testing the spectra of 6 different position points. The result shows that the spectral uniformity of xenon is good after filtering. Silicon cell was detected to have defection by electro-luminescence and the electric performance test was done. The value of Ⅰ-Ⅴ is different for discrepancy power 0.22 W by using the optical filter and without the filter. It indicates that the accuracy rating of electric performance testing is directly influenced by spectral marched degree of xenon.
