| titleOfInvention | Flake silver powder suitable for conductive adhesive of heterojunction solar cell and preparation method thereof |
| abstract | The invention discloses and provides a flake silver powder suitable for a conductive adhesive of a heterojunction solar cell and a preparation method thereof, including: obtaining a silver nitrate-ethylenediamine-ammonia precursor solution; Add the mixed dispersant solution into the silver nitrate-ethylenediamine-ammonia precursor solution, stir evenly, and keep at 15-20°C to obtain the first solution; add the reducing agent The solution is mixed with the ether antifoaming agent solution to obtain a second solution; the second solution is added to the first solution to carry out reduction reaction, washing, suction filtration of silver powder, vacuum drying and sieving to obtain spherical silver powder; After mixing with zirconia beads, ethanol and oleic acid dispersant are added in sequence, followed by vibration ball milling, sieving, ethanol washing and drying to obtain flake silver powder. The high tap density flake silver powder of the present invention can be applied to the conductive adhesive of heterojunction solar cells. |
