Original Abstract

This article deals with local defects (fractures) on edges of silicon solar cells. We observed a particular type of structural defects by an electron microscope. These defects can be regarded as surface texturization breaks. Specimens including this type of local defects have been put under investigation. We study weak radiation generated from reverse-biased defect active area by means of a photomultiplier and a scientific CCD camera. This approach proves to be useful to measure micro-scale surface imperfections and fractures. We also focused on thermal degradation in stressed regions. To this aim we used an infrared camera and it turns out that temperature degradation could affect larger regions compared to micro-scale defects.
