Abstract

The invention relates to the field of solar cells, in particular to a silicon oxide film forming machine for preparing an automatic alternating type solar cell. The technical problems that manual taking and placing consumes a large amount of time, the production efficiency is reduced accordingly, hydrogen can form bubbles to be gathered on the lower surface of a silicon wafer, and the sufficient reaction of the silicon wafer and reaction liquid can be affected by the existence of the bubbles are solved. According to the technical scheme, the automatic alternating type silicon oxide film forming machine for preparing the solar cell comprises a reaction box, a supporting frame and the like; a support frame is arranged on the left of the reaction box. According to the invention, automatic rotation of the silicon wafers is realized, the next silicon wafer is rapidly replaced to a reaction position, the overall production efficiency is improved, bubbles formed on the lower surfaces of the silicon wafers are dispersed, the reaction of the silicon wafers is not influenced by the bubbles, the dispersed bubbles are gathered and punctured, excessive bubbles are not remained in the reaction liquid, and the production efficiency is improved. And the dispersion state of the titanium dioxide particles is prevented from being influenced by the existence of bubbles.

Description

technical field [0001] The invention relates to the field of solar cells, in particular to an automatic rotation type silicon oxide film forming machine for preparing solar cells. Background technique [0002] The prior art Chinese patent CN103594557A requires PECVD or other deposition equipment for the existing method of preparing a silicon oxide film. On the one hand, such equipment is expensive, and at the same time, a complex deposition process is required to ensure film thickness and quality. Therefore, it is necessary to find a simple and easy-to-operate preparation process for a silicon oxide film. A method for preparing a silicon oxide film for a crystalline silicon solar cell is disclosed. The silicon wafer surface is oxidized in the nano-TiO2 aqueous dispersion to form a silicon oxide film with a controllable thickness, which overcomes the need to use PECVD or other deposition equipment in the existing method for preparing silicon oxide film. On the one hand, such ...
