Abstract

The invention relates to the field of solar cell manufacturing, in particular to a solar cell optical corrosion device. The technical problem to be solved by the invention is to provide a solar cell optical corrosion device. A solar cell optical corrosion device comprises a laser grooving mechanism, a hot air corrosion mechanism and the like. The middle of the inner top of the mounting frame is inbolted connection with the first hydraulic cylinder fixing frame. According to the invention, irregular laser simulation disorder engraving lines are carried out on the surface of the solar cell by using a blackbody effect, solar energy absorption efficiency is improved, the liquid level is even, the agentia spreading and corrosion carving progress is unified, all parts of the carving groove arein sufficient contact with the corrosion agentia through hot air surrounding blowing, the corrosion efficiency is improved, the situation that bubbles are mixed and cannot be corroded is prevented, solar energy utilization is increased through the reflection frequency of light in the rough carving groove after corrosion, and the solar panel curing efficiency is improved.

Description

technical field [0001] The invention relates to the field of solar cell manufacturing, in particular to a solar cell optical etching device. Background technique [0002] In the existing production of solar panels, in order to improve the efficiency of curing solar energy on the solar panel, a layer of anti-reflection film is attached to the surface of the solar panel. The design of the anti-reflection film directly affects the reflectivity of the solar cell to the incident light. The increase in efficiency plays a very important role. [0003] In summary, it is necessary to develop a laser simulation disorder engraving circuit on the surface of solar cells using the black body effect, so that the incoming light should not be continuously reflected and emitted, and the absorption efficiency of solar energy can be improved. Spread evenly to make the corrosion engraving progress on the solar surface uniform, and then use hot air to blow around to make the agent move in the en...
