Counter Electrode Based on PEDOT:PSS - TiO2 NTs Films for Dye-sensitized Solar Cells

摘要

A new dye-sensitized solar cell (DSSC) counter electrode was obtained through the electropolymerization of the monomer 3.4-Ethylendioxythiophene (EDOT) directly onto a indium tin oxide (ITO) coated glass in the presence of an aqueous titania nanotubes (TiO2 NTs) suspension. The TiO2 nanotubes in the anatase phase were incorporated in the conductive polymer film, being also observed an increase in the catalytic activity and the fill factor of the assembled device when using the under examination counter electrode.
