Solar cell assembly testing instrument with pulse xenon lamp linear light source bench

The solar cell assembly testing instrument adopts pulse xenon lamp linear light source and paraboloid scattered reflection, filtering system and silk screen between the light source and the test plane, for required light homogeneity and spectrum. It has constant voltage electronic load for measurement, open circuit voltage testing circuit, and linear light sources controlled by the xenon lamp power circuit. The photocurrent of the tested assembly under constant voltage is latched, sampled and stored by the computerized measurement and control mechanism. Under inconsistent light pulse, the present invention can measure the electric performance of the tested assembly and obtain I-V curve accurately by means of spot-by-spot flash measurement and measured data fitting.
