| titleOfInvention | Sliver electrode slurry for back electric field of silicon solar cell and preparation method thereof |
| abstract | The invention discloses sliver electrode slurry for a back electric field of a silicon solar cell and a preparation method thereof, and the silver electrode slurry for the back electric field of the silicon solar cell comprises the following components by weight percent: 60-70% of spherical silver powder, 0-5% of flaky silver powder, 2-6% of glass powder with a high-temperature softening point, 1-3% of glass powder with a low-temperature softening point and 20-30% of organic bonding agent. The particle size of the spherical silver powder is 0.5-2.5 mu m, and the tap density is above 4.5g/ml; the particle size of the flaky silver powder is below 5 mu m, and the tap density is above 4.0g/ml; and the glass powder with the high-temperature softening point is a PbO3-B2O3-SiO2-ZnO glass system, and the glass powder with the low-temperature softening point is a Bi2O3-B2O3-SiO2 glass system. The slurry is applied to a sliver electrode of the back electric field of the silicon solar cell; furthermore, after fast high-temperature sintering by a chained belt furnace, the adhesive capability is strong, the soldering resistance is good and the photoelectric conversion efficiency of a product is high. |
