Abstract: Forming a conductive film comprising depositing a non-conductive film on a surface of a substrate, wherein the film contains a plurality of copper nanoparticles and exposing at least a portion of the film to light to make the exposed portion conductive. Exposing of the film to light photosinters or fuses the copper nanoparticles.

Abstract: A solution of metal ink is mixed and then printed or dispensed onto the substrate using the dispenser. The film then is dried to eliminate water or solvents. In some cases, a thermal curing step can be introduced subsequent to dispensing the film and prior to the photo-curing step. The substrate and deposited film can be cured using an oven or by placing the substrate on the surface of a heater, such as a hot plate. Following the drying and/or thermal curing step, a laser beam or focused light from the light source is directed onto the surface of the film in a process known as direct writing. The light serves to photo-cure the film such that it has low resistivity.

Abstract: A highly transparent and electrically conductive substrate is made by applying a conductive mesh over a transparent substrate, depositing a UV-curable transparent material over the conductive mesh and the transparent substrate, and exposing the UV-curable transparent material to a directional UV light from a UV light source positioned so that the UV light emitted from the UV light source travels through the transparent substrate before being received by the UV-curable transparent material, wherein the UV-curable transparent material is cured in response to exposure from the UV light except for those portions of the UV-curable transparent material masked from exposure to the UV light by the conductive mesh. Uncured portions of the UV-curable transparent material are removed, and a transparent conductive material layer is deposited over the cured UV-curable transparent material and conductive mesh.

The CNT ink is dispensed into wells and allowed to dry so as to formed a cathode structure. It is important to note that after the CNT ink is deposited to form a cathode structure, no further post-deposition processes are performed, such as the removal of sacrificial layers, which could damage the CNT ink.
