Abstract: Transparent conductors and methods of forming same are provided. A transparent conductor can include a nanostructure layer and a low sheet resistance grid disposed on a transfer film surface having an acceptable level of surface roughness. The presence of the low sheet resistance grid lowers the sheet resistance of the transparent conductor to an acceptable level. After release of the transparent conductor from the transfer film, the surface roughness of the transparent conductor will be at least comparable to the surface roughness of the transfer film.
