摘要
通过对太阳模拟器的光谱测试研究发现：未采用滤光片的太阳模拟器中氙灯辐射的800~900 nm,900~1100 nm红外波段占总光谱波段400~1100 nm的百分比远远大于国际标准规定的匹配度,导致其相对光谱的能量分布不能满足A级或B级要求,严重影响太阳电池的测试结果。因此,该模拟器通过加入特别设计的滤光片对光谱加以矫正,滤除或减弱部分红外波段的辐射能量,使其能满足A级或B级光谱的要求,再通过对滤光片的优化设计,进而使得模拟光谱达到最佳均匀性。
The spectral test of solar simulator is carried out. The test result shows that the energy of the spectra from 800 to 900 nm and from 900 to 1100 nm which are radiated by the xenon lamp from solar simulator without laying optical filter occupies too much percentage of the whole spectra and is greater than that of the international standard code matching limit. Then it results in that the relatively spectral distribution of energy cannot fulfil the demand of A or B grade, which seriously affects the solar cell test result. So solar simulator needs to lay special designed optical filter to remedy the spectra, and the optical filter can filter or weaken energy of infrared band and fulfil the spectral demand of A or B grade. By optimal design of optical filter, we can make the spectrum to reach optimal uniformity.
