Embodiment １

[0033] After the silicon wafer has gone through the processes of texturing, diffusion, edge etching, and phosphorous silicate glass removal, it enters the process of coating the anti-reflection film 3 .

[0034] The baffle plate 2 of the present example adopts graphite material, and the specific implementation process is as follows:

[0035] ① Put the silicon wafer 4 from which the phosphosilicate glass is removed into the graphite carrier 5;

[0036] ② Place the customized graphite baffle 2 at a position 1 cm above the graphite carrier 5;

[0037] ③ Carefully observe and adjust the position of the baffle 2, so that the hollow pattern on the baffle 2 is located directly in front of the surface 3 coated with the anti-reflection film of the silicon wafer 4;

[0038] ④Fix the baffle 2 to ensure that during the process of coating 3, the baffle 2, the silicon wafer 4 and the graphite carrier 5 are kept in a relatively static state without displacement;

[0039] ⑤ Put the baffle p...

Abstract

The invention belongs to the technical field of solar cell manufacturing, in particular to a method for manufacturing colour solar cell with different colours in single cell. The manufacturing method includes that a baffle is added before a silicon slice in the process that the silicon slice is plated with antireflection coating, and the thickness variation of antireflection coating on silicon slice surface is controlled, so that cell can be in different colours, and a colour cell with different colours in single cell is formed. The controllability and repeatability of the invention are good, flexibility is high, colorization in small area can be realized, and beautiful requirement of solar cell in building integration 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 colored solar cell. 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] At present, the production of the anti-reflection film of the solar cell mainly adopts the method of plasma enhanced chemical vapor deposition (PECVD). The thickness of the anti-reflection film is the same, and the color is single, 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 o...
