Embodiment Construction
[0049] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0050] Such as figure 1 Shown: a test device for the linearity of solar cells with high light and strong range of light, including a test light source capable of generating light pulses and a test darkroom. The device uses a pulse xenon lamp 1 to generate millisecond-level high-energy light pulses as a test light source. The xenon lamp has an elliptical concave reflector 2 that focuses the light beam. When a pulsed xenon lamp cannot meet the high light intensity required, multiple pulsed xenon lamps can be triggered simultaneously through a synchronous trigger circuit, using a tapered light tube 3 or a cone-shaped fiber bundle or other optical paths. The system combines the light radiation of multiple pulsed xenon lamps to achieve higher light intensities. The test darkroom 14 has a small hole window 4 in the light axis direction of the light source, and the...
