Improved Carbon Counter Electrodes for Dye Sensitized Solar Cells

Abstract:

We fabricated improved carbon counter electrodes to improve conversion efficiency of dye sensitized solar cells (DSSCs). Unlike conventional carbon counter electrodes, we added small quantity of TiO2 nano powder and used chemical sintering methodology developed by Park’s group to make surface morphology of the electrodes to change. Through these methods, we could observe change of surface morphology of carbon electrodes and influences on short circuit current density (JSC) and conversion efficiency.
