Systems and methods for optimizing morphology and electrical properties of silver printed on a substrate with a particular implementation in photovoltaic manufacturing techniques. The system comprises a substrate, a printer jet head having a nozzle to dispense a reactive metal ink and a solvent onto the substrate, and wherein the solvent and a temperature of the substrate are controlled during deposition of the reactive metal ink onto the substrate to produce a dense film in the absence of sintering.

Systems and methods for controlling the morphology and porosity of printed reactive inks for high precision printing

Methods and chemistries are described to form electrically conductive adhesion promoters for use with reactive inks. In some implementations, a metal ink is printed on a substrate. An adhesion promoter is deposited on the surface of the substrate. The adhesion promoter reacts to form a covalent bond with the substrate. Subsequently, a reactive metal ink is used to print on a substrate using a drop-on-demand printing process. The reactive metal ink includes metal cations that react with the adhesion promoter-treated substrate surface to form a conductive bond between the adhesion promoter-treated substrate surface and a metal of the reactive metal ink.
