[0002] Solar cells are generally categorized into monocrystalline silicon, polycrystalline silicon, and amorphous silicon. Monocrystalline silicon solar cells are the fastest-growing type of solar cell. Their structure and production process are finalized, and the products are widely used in space and on the ground. These solar cells are made from high-purity monocrystalline silicon rods. To reduce production costs, solar cells for terrestrial applications use solar-grade monocrystalline silicon rods. CV5, or flexible transport platform, is often used in cell defect detection.

[0003] Because black and white cameras can only capture the brightness information of the subject but not the color information, the image presented is a black and white grayscale image. By detecting the edges in the image, the contour information of the object can be extracted. Therefore, black and white cameras are generally used to detect battery cell defects. The loader transmission method is flexible belt transmission, that is, the battery cell is transferred to the bottom of the black and white camera by rotating the belt to take pictures and detect battery cell contour defects. However, due to structural problems, the battery cell and the belt overlap, and the overlapping part is missed because the images of the battery cell and the belt are both black.
