Abstract：Aiming at the Kirkendall gap appeared in passivation layer of the PERC solar cell at present，this paper designs a PERC solar cell detection system based on electroluminescent image identification. Based on the principle of electroluminescence，the hardware structure of the detection system is designed，and the collected electroluminescent images are clear and bright. At the same time，the software development of the detection system is completed. The software can accurately identifies the battery defects such as black spots and black lines in the electroluminescent images，which provides an effective experimental means for the analysis of the electroluminescent characteristics of PERC cell.
Keywords：PERC solar cell；electroluminescence；image identification
