Embodiment Construction
[0032] Such as figure 1 , the inventive method comprises the following steps:
[0033] 1), prepare the measurement device, including xenon lamp light source 1, focusing lens 2, monochromator 5, monochromatic optical power meter, digital source meter 9, microcomputer 10 and sample holder 8, focusing lens 2 adopts quartz plano-convex lens, solar cell The positive and negative poles of the sample 7 are short-circuited to the digital source meter 9, and the sample rack 8 is arranged in the sample chamber 6. The sample chamber is a dark room made of light-absorbing material to shield stray light. The solar cell sample 7 is fixed on the sample rack 8, and the sample rack 8 Built-in electronic temperature control device;
[0034] 2), use the characteristic line of the mercury lamp spectrum to calibrate the monochromator 5, firstly calibrate level 0, and then calibrate level 1: choose a characteristic line of mercury for calibration;
[0035] 3), adjust the xenon lamp light source 1...
