The counter electrode in the dye-sensitized solar cells (DSSCs) plays a role in regenerating the oxidized sensitizer through the reduction of the redox species after electron injection. Due to the high conductivity and electro-chemical stability, conducting polymers have the potential to replace platinized counter electrodes in DSSCs. Among them, poly(3,4-ethylenedioxythiophene)(PEDOT) is of special interest because of its high conductivity, electrochemical reversibility, transparency, stability, and high catalytic activity compared to other conducting polymers. PEDOT nanofibers with a diameter of 50-100 nm were fabricated by microemulsion polymerization method. The PEDOT nanofibers were coated onto fluorine-doped tin oxide (FTO) substrate to use as counter electrodes in DSSCs. The performance of the PEDOT nanofibers-based DSSCs was characterized by cyclic voltammetry and current density-voltage measurements. |
