Description

Technical Field

[0001] The utility model belongs to the field of perovskite solar cell production, and specifically relates to an etching device for perovskite solar cell production. Background Art

[0002] The perovskite solar cell of the prior art is a solar cell that uses a perovskite-type organic metal halide semiconductor as a light-absorbing material. It belongs to the third generation of solar cells, also known as new concept solar cells. During the processing, etching technology is required. Etching is a technology that removes materials by chemical reaction or physical impact. The protective film of the area to be etched is removed, and it comes into contact with a chemical solution during etching to achieve the effect of dissolution and corrosion, forming a concave-convex or hollow molding effect.

[0003] The Chinese patent with the announcement number CN212461609U discloses an etching device for perovskite solar cell production, which relates to the technical field of perovskite solar cell production, and solves the problem that the existing etching device has poor etching effect on solar cells. A cross water collecting pipe is arranged inside the shell, and the cross water collecting pipe is fixedly connected to the shell, and an atomizing nozzle is installed at the lower end of the cross water collecting pipe. The etching liquid is pressurized and ejected through the atomizing nozzle, and gradually covers the upper end of the solar cell in an atomized state, and is thickened layer by layer, so that the etching liquid can be evenly distributed on the upper end of the solar cell.

After the etching of the solar cell is completed, the placement plate on which the solar cell is placed is below the atomizing nozzle. When the solar cell is taken out, residual water droplets from the upper atomizing nozzle may fall on the staff and cause corrosion, making it inconvenient to take the solar cell.

[0005] In view of this, the present utility model is proposed. Summary of the invention
