What is the role of the EL detector for solar cell module defects?

The solar cell module defect EL detector uses the electroluminescence principle of crystalline silicon to capture the near-infrared image of the module with a high-resolution infrared camera to obtain and determine the defect of the module. The infrared detection can comprehensively grasp the internal problems of the solar cell, provide a basis for improving the production process to improve product quality, and can timely repair the problem module to reduce losses as much as possible. keywords：
