| titleOfInvention | Slurry for PERC battery and preparation method thereof |
| abstract | The invention provides a slurry for PERC battery and a preparation method of the slurry, the slurry includes a conductive phase, a glass phase and an organic binder, and the conductive phase includes aluminum powder and aluminum alloy powder; The glass phase includes glass frit and auxiliary glass frit, and the softening temperature of the auxiliary glass frit is higher than the softening temperature of the glass frit. The slurry includes: 65-73 parts by mass of aluminum powder, 3-10 parts by mass of aluminum alloy powder, 1.8-2.2 parts by mass of glass powder, 0.3-0.5 parts by mass of auxiliary glass powder and 15-40 parts by mass of organic binder. The slurry is ground and dispersed by mixing the aforementioned aluminum powder, aluminum alloy powder, glass powder, auxiliary glass powder and organic binder, and its fineness is not more than 15 μm. The slurry is suitable for the back metallization process of PERC cells, simplifies the production process of PERC cells, it can burn through the passivation film, form a stable aluminum-silicon contact, effectively control the back surface recombination, and has a wide process adjustment window and stable performance. . |
