Transparent conducting electrodes include a doped single walled carbon nanotube film and methods for forming the doped single walled carbon nanotube (SWCNT) by solution processing. The method generally includes depositing single walled carbon nanotubes dispersed in a solvent and a surfactant onto a substrate to form a single walled carbon nanotube film thereon; removing all of the surfactant from the carbon nanotube film; and exposing the single walled carbon nanotube film to a single electron oxidant in a solution such that one electron is transferred from the single walled carbon nanotubes to each molecule of the single electron oxidant.
