Abstract
A solution process is provided for forming a textured transparent conductive oxide (TCO) film. The process provides a substrate, and forms a first layer on the substrate of metal oxide nanoparticles such as ZnO, InO, or SnO. The metal oxide nanoparticles have a faceted structure with an average size greater than 100 nanometers (nm). Voids between the metal oxide nanoparticles have a size about equal to the size of the metal oxide nanoparticles. Then, a second layer is formed overlaying the first layer, filling the voids between the nanoparticles of the first layer, and completely covering the substrate. The result is a continuous TCO film having an average surface roughness that is created by the combination of first and second layers.
