The Effects of Sputtering Pressure on the Properties of Carbon Counter Electrodes for Dye-Sensitized Solar Cells

Abstract:

The carbon counter electrodes for Dye-sensitized solar cells (DSSCs) were deposited on FTO glass using graphite target by bipolar pulse magnetron sputtering. The effects of sputtering pressure on the structures and properties for carbon films were investigated. The carbon bond structure was analyzed by Raman spectra. The sheet resistance of carbon film was detected by four-probe tester. The transmittance was tested by UV-visible spectrum. The performance of DSSCs was tested by solar simulator after the cells assembled. The results indicated that the ratio of ID/IG reduced, the degree of graphitization decreased, sheet resistance raised, transmittance increased and photoelectric conversion efficiency reduced with the increasing of sputtering pressure.
