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.
