PEDOT nanotube arrays present a better catalytic activity with I − /I 3 − redox than standard platinized counter electrodes used for dye sensitized solar cells exhibiting thereby a photoconversion efficiency as high as 8.3%. The PEDOT layer introduces an additional series resistance which is compensated by its excellent catalytic performance yielding counter electrodes as good as platinized ones, or even better.
