Description

Technical Field

[0001] This application relates to the field of photovoltaic cell cleaning technology, and in particular to a cleaning tank with a bubbling tube structure. Background Technology

[0002] In the manufacturing process of solar cells, silicon wafers undergo multiple processes such as slicing, grinding, chamfering, and polishing, resulting in various impurities adsorbed on their surface. Before diffusion, they need to be cleaned to remove these contaminants and to create a textured surface structure (texturing) that reduces sunlight reflection. The cleanliness of the cleaning directly affects the yield and reliability of the solar cells.

[0003] The existing cleaning tank with a bubbling tube structure has a partition that divides the tank into an inner tank and an outer tank. The silicon wafers are placed in the inner tank for cleaning, and the liquid at the top of the inner tank overflows towards the outer tank. The outer tank filters the liquid and returns it to the inner tank from the bottom to achieve liquid recycling. To improve the circulation effect, a bubbling tube is installed at the bottom of the tank for bubbling. The existing bubbling tube is connected to the tank from the outside and welded to the bottom of the tank. Because the liquid used for cleaning silicon wafers is at a high temperature, and because the bubbling tube structure is located outside the tank and connected to the tank through a union, the plastic pipe of the bubbling tube is subjected to uneven stress and severe deformation due to the temperature rise during operation.
