Embodiment １

[0024] After the silicon wafer 4 has gone through the processes of texturing, diffusion, edge etching, phosphosilicate glass removal, and passivation anti-reflection film 3 deposition processes; a high-temperature-resistant adhesive tape 1 with a hollow pattern is pasted on the surface of the silicon wafer 4, wherein the high-temperature-resistant adhesive tape 1 and No obvious gaps are left between the passivation anti-reflection films 3; then the silicon wafer 4 with the high temperature resistant adhesive tape 1 attached is put into the deposition chamber of the reflective film or the color modulation film 2 for the second deposition; the second deposition will be completed The deposited silicon wafer 4 is taken out from the deposition chamber and cooled to room temperature; the high-temperature-resistant adhesive tape 1 is torn off, and then the steps of printing and sintering of the back electrode, the back field, and the positive electrode are completed successively, and t...

Abstract

The invention, which belongs to solar cell sheet producing technology field, specifically relates to a manufacturing method of a solar cell sheet with color patterns. The manufacturing method comprises the following steps: pasting a high-temperature resistant adhesive tape possessing specific hollow out patterns on a silicon chip with a passivation antireflection film; then carrying out again deposition of the antireflection film or a color modulation film; finally removing the high-temperature resistant adhesive tape so as to form the color patterns which are corresponding to the hollow out patterns on the adhesive tape. The method of the invention has good controllability, good repeatability and high flexibility. The application of the method can make the solar cell sheet to satisfy a beautiful demand in building integrated photovoltaics.

Description

technical field [0001] The invention belongs to the technical field of making solar cells, and in particular relates to a method for preparing solar cells 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 mat...
