Solar cell panel defect detection system and method based on CIS image acquisition

Abstract

The invention discloses a solar cell panel defect detection system and a solar cell panel defect detection method based on CIS image acquisition. The solar cell panel defect detection system comprises a conveying device, an image acquisition device and a data processing module, wherein the image acquisition device is arranged right above the conveying device, and the image acquisition device is connected with the data processing module; and a solar cell panel is transported by means of the conveying device, the image acquisition device acquires an image of the solar cell panel and transmits the image to the data processing module when the solar cell panel passes beneath the image acquisition device, and the data processing module performs defect analysis and detection on the acquired image. According to the solar cell panel defect detection system and the solar cell panel defect detection method, image acquisition is performed by means of the image acquisition device, real-time performance is improved and cost is reduced, defects of the detected solar cell panel comprise unfilled corners, edge breakage, openings or holes and contamination, various defect types can be detected and detection efficiency is ensured. The CIS image acquisition system is utilized to acquire images, the image acquisition rate can be improved, the real-time performance can be improved, and the cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of solar cells, and more specifically relates to a solar cell defect detection system and method based on CIS image acquisition. Background technique [0002] As a free, clean, safe and abundant renewable energy, solar energy is more and more favored by people. As a device that converts solar radiation into photothermoelectricity or direct photoelectricity, solar cells are becoming more and more popular in the research of manufacturing and testing. [0003] As the core device of solar cells, the quality of the manufacturing process of solar cells directly affects the power generation efficiency, short-circuit current, open-circuit voltage, and service life of solar cells. The manufacturing process needs to go through two parts: cutting and texturing, and then chemical corrosion and cleaning to remove the surface damage layer. Because solar cells are fragile, during the production process (surface corrosion...
