Cobalt Sulfide as Counter Electrode in p-Type Dye-Sensitized Solar Cells
Abstract
We proposed a novel application of cobalt sulfide (CoS) in the configuration of transparent thin film as anode in p-type dye-sensitized solar cell (p-DSC). The anodes here considered have been prepared using a water-based method that is suitable for the large scale production of large-area electrodes. The photoactive cathodes of the p-DSC were mesoporous nickel oxide (NiO) thin films deposited via rapid discharge sintering. The NiO electrodes were sensitized with the benchmark dye erythrosine B (ERY), while the couple I−/I3− was the redox mediator. The CoS anodes showed higher electrocatalytic efficiency in comparison with the commonly used platinized Fluorine-doped Tin Oxide (Pt-FTO). This was determined by means of electrochemical impedance spectroscopy of CoS based dummy cells, with CoS showing a lower charge-transfer resistance with respect to Pt-FTO. The overall conversion efficiency of the p-DSC employing ERY-sensitized NiO as photoactive cathode and CoS anode was 0.026 %, a value very close to that obtained with Pt-FTO anodes (0.030 %). The external quantum efficiency spectra of the p-DSCs with CoS anodes were similar to those obtained with Pt-FTO anodes under illumination with AM 1.5 solar simulator.
