Title:
PASTE FOR N-TYPE SOLAR CELL FRONT FINE GRIDS AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/042419
Kind Code:
A1
Abstract:
A paste for N-type solar cell front fine grids, comprising in parts by weight: 1-5 parts of a high-activity glass powder, 1-5 parts of silicon powder, 75-79 parts of aluminum silicon alloy powder and 15-20 parts of organic components. The paste for N-type solar cell front fine grids and the preparation method therefor use an aluminum paste as a substitution for the aluminum silver doped paste in the prior art, reducing the production cost of a N-type solar cell, eliminating a grooving process before printing due to the high-activity glass powder contained in the aluminum paste, simplifying processing steps, causing no harm to a passivation layer and improving electrical performances of the solar cell.
