[0002] Relying on the continuous reduction of production costs and the improvement of photoelectric conversion efficiency in recent years, photovoltaic power generation has become a technology that can replace fossil energy. In the production process of solar cells, the silicon wafers have been processed through multiple processes such as slicing, grinding, chamfering, and polishing. Various impurities have been adsorbed on the surface of the silicon wafers. Before diffusion, they need to be cleaned to eliminate various pollutants and make a velvet structure (velvet making) that can reduce the reflection of sunlight on the surface. The cleanliness of the cleaning directly affects the yield and reliability of the solar cell.

[0003] In order to improve the efficiency of silicon wafer cleaning and texturing, a horizontal chain wet chemical equipment has been developed. That is, the silicon wafer is driven by a horizontal chain transmission system to continuously pass through the wet chemical tank horizontally, so that the surface of the silicon wafer is chemically acted on by the solution. This type of horizontal chain wet chemical equipment can realize continuous dynamic silicon wafer processing because the silicon wafer passes through the wet chemical tank horizontally and continuously, thereby effectively improving production efficiency; the silicon wafer that has undergone surface chemical reaction treatment in the wet chemical tank continues to enter the subsequent cleaning tank driven by the horizontal chain transmission system for surface cleaning, and then continuously enters the drying tank for drying.

[0004] However, due to the unreasonable layout of the drying tank of the above-mentioned horizontal chain wet chemical equipment in the industry, the space utilization rate is poor and maintenance is difficult; in addition, the internal piping of the equipment uses hoses, which are costly and the messy distribution of the hoses affects the appearance.
