Abstract Aiming at the measure problem of crack of silicon solar cells, an infrared noncontact detection method was used. The electroluminescence image of silicon solar cells was captured by CCD camera. Image preprocessing, image segmentation, feature extraction and image identification were analyzed based on Matlab image processing. The result proves that, using the principle, crack of silicon solar cells can be detected.
