A Novel Poly(3,4-ethylenedioxythiophene)‎-graphene OxideTitanium Dioxide Composites Counter Electrode for Dye-Sensitized Solar Cell

الملخص EN

PEDOT-based material counter electrodes (CEs) are recently given an enormous attention as new renewable energy sources due to their cost-effectiveness and accessibility, coupled with the simplicity of production.

The existing dye-sensitized solar cells (DSSCs) are expensive because they are made using platinum-based glass electrode.

In this work, a new CE, that is, poly(3,4-ethylenedioxythiophene)-graphene oxide/titanium dioxide (PEDOT-GO/TiO2) with a low charge transfer resistance (Rct=9.0 Ω), was fabricated.

In addition, PEDOT-GO/TiO2 CE possesses a good electrocatalytic activity (ECA) toward the tri-iodide ions reduction and an improved efficiency of 1.166% was reached in DSSC.
