The present disclosure relates to a conductive paste based on seed silver powder and a preparation method therefor, belonging to the technical field of photovoltaic cells. The conductive paste includes 10-85 wt % seed silver powder, 2-5 wt % glass frit, and 8-12 wt % organic vehicle, with the balance being spherical silver powder. The seed silver powder uses base metal powder as a matrix. Silver is grown on the surface of the matrix via liquid-phase reduction using a supported agent. After calcination, multiple silver pores are formed in the surface of the base metal powder. After photoinduced silver electroplating, “silver anchors” are formed interspersed in the sintered layer. This increases the contact area between the sintered layer and the electroplated layer, reduces the resistivity of the grid electrode, enhances the interlayer bonding strength, mitigates resistance increase, effectively improves the photoelectric conversion efficiency, and reduces the cost of the conductive paste.

The invention discloses a megasonically exfoliated two-dimensional (2D) nanomaterial ink. The megasonically exfoliated 2D nanomaterial ink is then aerosol-jet printed (AJP) onto printed graphene electrodes to achieve all-AJP, flexible photodetectors. The 2D nanomaterial AJP ink is designed with terpineol, a high boiling point solvent, which enables a highly ordered thin-film morphology and also improves the photogenerated charge transport. After printing, the photodetectors are photonically annealed, which provides quasi-ohmic contacts and photoactive channels with responsivities that outperform previously reported all-printed visible photodetectors by over 3 orders of magnitude. Megasonic exfoliation coupled with AJP allows the superlative optoelectronic properties of ultrathin nanosheets to be utilized in the scalable additive manufacturing of mechanically flexible optoelectronics.
