The invention discloses a flower basket device for placing a silicon wafer. The flower basket device comprises side rods provided with gear teeth, bottom rods, pressure rods provided with gear teeth,and oppositely arranged supporting bottom stands, wherein the two ends of the bottom rods are respectively connected with the bottom ends of the supporting bottom stands; the two ends of the side rodsare respectively connected with two transverse ends of the supporting bottom stands; the side rods are located above the bottom rods; the pressure rods are located at the top ends of the supporting bottom stands; and the gear teeth on the side rods are gear teeth provided with through holes to allow the silicon wafer to be placed between the adjacent gear teeth provided with the through holes. According to the flower basket device, the gear teeth on the side rods are the gear teeth provided with the through holes, and when the flower basket device placed with the silicon wafer is placed intoa medicine groove, medicine liquid in the medicine groove can flow by the through holes in the gear teeth, so that the contact area of the medicine liquid and the silicon wafer is increased; a reaction rate of the medicine liquid and a region of the gear teeth corresponding to the surface of the silicon wafer is accelerated; the problem of hot spot generation on the surface of the silicon wafer iseffectively solved; generation of a flower basket mark can be effectively solved; the quality of the surface of the silicon wafer is improved; and the attractiveness of the appearance of a manufactured battery piece is further improved.
Description
technical field [0001] The present application relates to the technical field of solar cells, in particular to a flower basket device for placing silicon wafers. Background technique [0002] With the continuous development of the solar cell industry, improving the performance of the solar cell has always been a goal pursued by the solar cell industry. Texturing is the first process of manufacturing crystalline silicon cells. The effective texture structure can make the incident light reflect and refract multiple times on the surface of the silicon wafer, reduce the reflectivity of light, increase the amount of light absorbed by the silicon wafer, and finally make solar energy The photoelectric conversion efficiency of the battery is improved. [0003] The flower basket device is a carrying tool for placing silicon wafers. During texturing, the silicon wafers need to be placed in the flower basket device, and then put into the medicine tank as a whole to react with the corr...
