Micro cracks are tiny tears in solar cells stemming from haphazard shipping and installation or defects in manufacturing. While these micro-cracks do not lead to immediate energy production loss, weather changes, and general wear and tear can contribute to their growth over time and make them a more significant issue.
A solar cell defect detection method with an improved YOLO v5 algorithm is proposed for the characteristics of the complex solar cell image background, variable defect morphology, and large-scale differences. First, the deformable convolution is incorporated into the CSP module to achieve an adaptive learning scale and perceptual …
