[0002] Crystalline silicon batteries are solar cells made of crystalline silicon materials, including monocrystalline silicon solar cells and polycrystalline silicon solar cells. Currently, silicon-based silicon solar cells are widely used in ground photovoltaic systems. Due to the inherent characteristics of the crystal structure, crystalline silicon battery wafers are very prone to cracking. The production process of crystalline silicon components is long, and many links may cause hidden cracks in the battery wafers.

[0003] In order to ensure the quality of products, it is necessary to detect the safety of crystalline silicon batteries. During detection, it is necessary to detect the positive penetration hidden crack defect and the oblique penetration hidden crack defect of the crystalline silicon battery respectively. However, some detection devices can only perform single detection, which increases the detection time. At the same time, if there is dust attached to the surface of the crystalline silicon battery, it will also affect the detection effect of the battery. Therefore, it is necessary to propose a safety detection platform for crystalline silicon batteries. Content of the Utility Model
