Embodiment １

[0016] The silicon wafer 3 enters the process of making the mask 1 and chemical etching after the processes of texturing, diffusion, edge etching, phosphosilicate glass removal, and anti-reflection coating 2 processes.

[0017] This example mask 1 adopts paraffin, and chemical reagent adopts the phosphoric acid solution that mass ratio is 10%, and specific implementation process is as follows:

[0018] A. The surface of the silicon wafer 3 coated with the antireflection film 2 is printed on the surface of the silicon wafer 3 with the mask 1 by spray printing;

[0019] B. Put the silicon wafer 3 with the mask 1 into a phosphoric acid solution with a concentration of 10%, and chemically etch it for 3 minutes;

[0020] C. Wash the silicon wafer 3 corroded by phosphoric acid in deionized water for 1 minute, and then put it in dewaxing water or trichlorethylene solution to remove the paraffin mask 1;

[0021] D. Put the silicon wafer 3 from which the mask 1 has been removed into d...

Abstract

The invention belongs to the technical field of solar battering plate manufacturing, and in particular relates to a method for preparing a solar battery plate with color patterns in a single chip. The preparation method comprises the following steps: preparing a mask with hollow patterns on a silicon chip on which a reflection film is coated; corroding an antireflection film by a chemical agent; removing the mask after the corrosion, thus a color battery plate with color patterns in the chip is formed. According to the invention, the controllability and repeatability are good, the flexibilityis high, the colorization in a small area can be realized, and the requirement of beauty in the building integration for the solar battery plate can be met.

Description

technical field [0001] The invention belongs to the technical field of solar cell production, and in particular relates to a method for preparing a solar cell with color patterns. Background technique [0002] The production process of the battery sheet is texturing, diffusion, etching, anti-reflection coating, back electrode, back field, positive electrode printing, and sintering. [0003] Currently on the market, the color of the cells is mainly blue and black. After the components are packaged, the color of the components is relatively single. With the continuous progress of the photovoltaic industry, the market has put forward higher requirements for photovoltaic products, not only to ensure the continuous improvement of efficiency, but also to put forward more stringent requirements for the appearance of the cells. At present, a large number of photovoltaic power plants are under construction, and the integration of photovoltaics and buildings is becoming more and more...
