单色光电流-电压特性测试在碲化镉太阳电池研究中应用.

The monochromatic optical current-voltage characteristic performances of cadmium telluride solar cells with different structures were tested, and the collection efficiency at different wavelengths was calculated. The results show that high resistivity layer can greatly improve the collection efficiency of solar cell short-wave, and has a certain effect on the collection efficiency of long-wave. The back contact layer facilitates forming ohmic contact on the back of the solar cells. And the appropriate cadmium sulfide layer can improve the interface of window layer and improve the device performance of solar cells. The relationship between device structure and device performance is obtained by the measure method in order to provide theoretical and experimental basis for further optimization of battery structure and preparation technology and improvement of solar cell conversion efficiency.
