Abstract

This study is focused on testing methods determining quality of solar cells. Non-destructive methods are used for correct determination of defects by using of recombination effect of charge carrier in PN junction. Due to these methods can be the solar cell diagnosed and described. By using of various temperatures during the testing we can receive more objective results thanks to simulated operation conditions. Peltier cells are used for graditional change of temperature. Diagnostic and testing methods described in this study are based on emission of light and the recombination processes in PN junction. It is especially electroluminescence and photoluminescence method. For comparison it is used the observation of emitted light from microplasma method. Described methods detect materials and process defects due to use of lownoise and very sensitive CCD camera.
