Abstract
Method for creating an electrode on a substrate using a laser assisted deposition process. A metal paste is printed and dried on the substrate to form a conductive layer, and by 2D or 3D inspection, the dimensions of the conductive layer are measured. The substrate is subject to a pretreatment process so as to increase adhesion and/or conduction of the conductive layer to the substrate. An electrode that is produced according to the present method may be used in flexible devices.
Claims10
A method of fabricating an electrode, comprising:
- pretreating a substrate, wherein the pretreating comprises jetting metal, from a foil that has been coated with a metal layer, onto the substrate, and wherein the metal layer and the substrate are formed from different materials;
- depositing a paste layer onto the substrate by laser assisted deposition;
- drying the paste layer so as to form a conductive layer on the substrate;
- and
- repeating the depositing and drying steps so as to increase a height of the conductive layer.
