A self-cleaning transparent conductive surface includes a hydrophobic film and a metal nano-web coupled to the hydrophobic film. The metal nano-web imparts conductive properties to the surface of the film and texturing formed by either the hydrophobic film, substrate or metal nano-web create a super-hydrophobic surface. This super-hydrophobic and conductive surface may be created by etching and layering a metal nano-web over the surface of a hydrophobic film or a rigid substrate, the metal grid may the hydrophobic film or substrate may also be etched in a moth's eye pattern. Both the hydrophobic film or substrate and metal nano-web may be coated in a layer of hydrophobic material to further increase the hydrophobic effect.
