Abstract

The invention discloses a solar cell sheet electroplating equipment for improving the uniformity of electroplating, comprising an electroplating tank, an electroplating solution, a battery sheet and a silver anode, the electroplating tank is provided with an electroplating solution, and the battery sheet and the silver anode are arranged in the electroplating tank and immersed in the electroplating solution, the silver anode is set at the corresponding position under the battery sheet, and the shape of the silver anode is an upwardly convex arc in the middle, that is, the vertical distance between the middle of the silver anode and the battery sheet is the closest , the closer to the two ends of the silver anode, the farther the vertical distance between the silver anode and the cell. By changing the shape of the silver anode, the present invention makes the electric field received by each battery sheet more uniform, so as to obtain a more uniform electroplating weight gain, which will reduce the variance of this process and improve the quality of the product. Changing the shape of the silver anode is relatively simple to implement, without increasing costs and without changing the manufacturing process.

Description

[0001] technical field [0002] The invention relates to a metallization process of a solar cell, in particular to a solar cell electroplating equipment for improving the uniformity of electroplating. Background technique [0003] The metallization process is a very important process in the solar cell production process, and electroplating is an important method of the solar cell metallization process. Solar cells are put into the electroplating solution as the cathode during electroplating, and the silver plate made of pure silver is used as the anode at the opposite side of the cell, and the electroplating can be carried out by connecting the power supply between the two. [0004] like figure 1 and 2 Shown: conventional electroplating equipment comprises electroplating tank 1, electroplating solution 2, cell sheet 3 and silver anode 4, and described electroplating tank 1 is provided with electroplating solution 2, and described cell sheet 3 and silver anode 4 are arrange...
