PEDOT nanotube arrays present a better catalytic activity with I−/I3− 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.

PEDOT NANOTUBES M. Döbbelin , R. Tena-Zaera , P. M. Carrasco , J.-R. Sarasua , D. Mecerreyes , J. Polym Sci: A 2010 , 48 , 4648

Different contributions to the series resistance for cells prepared with electrolyte A and B. First row sheet resistance, Rs, second row charge transfer resistance between counter elecdrode and electrolyte, Rce

Sum of different contributions to the series resistance for cells prepared with electrolyte A and B.

PEDOT NT, exhibing photoconversion efficiency as high as 8.3%, the highest, as far as we know, for PEDOT CE

There are two different contributions in the effect of the counter electrode: R ce and R sheet

The performance of the counter electrode depends on the electrolyte

This work could have important implications in the current studies related with different electrolytes

PEDOT use like an electron transporter
