Embodiment 1

[0018] Example 1: Preparation of 156 polycrystalline silicon colored solar cells with a rabbit pattern.

[0019] First prepare a pattern with a rabbit pattern (such as figure 2 As shown) the screen; using screen printing technology, the Merck acid corrosion paste is printed on the color modulation layer of 156 polysilicon color solar cells; the solar cells printed with Merck acid corrosion paste will be completed at room temperature , placed for 15 minutes to complete the adjustment of the thickness of the color modulation layer; finally ultrasonically cleaned, sprayed with water on the positive electrode side with the pattern, and then dried to complete the production of the rabbit pattern of the color solar cell.

[0020] The above-mentioned obtained solar cells have electrical performance parameters of Efficiency: 16.3%; Pmmp: 3.94W; Isc: 8.046A; Voc: 0.626V; Impp: 7.545A; Compared with the sheet, its electrical performance parameters are basically not affected by pattern...

Embodiment 2

[0021] Example 2: Preparation of colored 125 single crystal solar cells with the word "POWER".

[0022] First prepare the screen plate with the pattern of "POWER", and use the method of screen printing to print Merck's acidic etching paste on the color modulation layer of the color 125 monocrystalline solar cell; the solar cell printed with the corrosive paste will be completed , placed at room temperature for 10 minutes to complete the adjustment of the thickness of the color modulation layer; finally ultrasonically cleaned, water sprayed on the positive electrode side with the pattern, and then dried to complete the production of the word "POWER" on the color solar cell.

[0023] The above-mentioned solar cells, Efficiency: 18.5%; Pmmp: 2.83W; Isc: 5.805A; Voc: 0.628V; Impp: 5.391A; Performance parameters are largely unaffected by patterning.

Abstract

The invention discloses a method for preparing a patterned colored solar battery sheet. The preparation process of the present invention can make arbitrary patterns locally on the surface of colored solar cells, the preparation process is simple, closely combined with the current production process, and can quickly realize industrialization; the color solar cells prepared by this method will not suffer from loss of electrical properties The method can be used to freely draw desired patterns on the colored solar cells to meet different needs and expand the application field of the colored solar cells; the method is used to make colored solar cells with patterns, which has simple structure, distinctive features and exquisite patterns. It is suitable for making decorations, meets different usage requirements, and has good energy-saving and environmental protection benefits.

Description

technical field [0001] The invention belongs to the technical field of preparation of colored solar cells, in particular to a method for preparing colored solar cells with patterns. Background technique [0002] In recent years, colored solar cells have developed to a certain extent in the market. The patent application number is 200910163738.9, which discloses a solar cell with a color modulation layer and a manufacturing method, which can present a predetermined color and integrate with the building. Meet different architectural appearance requirements. [0003] However, with the further development of the solar industry, due to factors such as environmental requirements, visual requirements, and decorative requirements, for example: when solar cells are used in solar flashlights and solar perpetual calendars, if the personalization and aesthetics of the products are considered, it is necessary to consider the use of solar cells. Corresponding patterns are matched on the ...
