Claim Text:
1. A method to patterning a conductive electrode comprising providing a substrate, coating a first solution comprising a first material on to the substrate to form a first layer of nanowire film; evaporating away the solvent in the metal nanowire film; positioning a mask above the metal nanowire film, wherein the mask has a repeated open space permitting UV light to pass through and some areas shielding UV light away from the nanowire film; shining UV light above the mask; converting the first material into a second material by a photo acid generator and UV light, wherein the first material and second material has a refractive index difference less than 0.2 and a haze difference of no more than 0.2%, and second material is less conductive than the first material; and annealing the film removing the unreacted photo acid generator in the area shielded by the mask, wherein the first material forms the first region in the patterned electrode and the second material forms the second region in the patterned electrode.
