ABSTRACT
Conductive thin films of Poly(3,4-ethylenedioxythiophene) (PEDOT) have been successfully deposited on a variety of substrates by a simple chemical vapor deposition (CVD) method starting from the liquid monomer (EDOT) and using FeCl3 as a catalyst. Resistivity measurements indicated very good conductivity of the material, comparable with other previously reported values for PEDOT deposited by CVD. Further cyclic voltammetry measurements indicated a value of around -4.7 eV for the HOMO level of PEDOT in the deposited films, in agreement with other reported values. This value is within the bandgap of most semiconductors, and together with the relative low internal resistance makes our material an ideal candidate as a solid-state hole transport material for dye sensitized solar cells.
