Synthesis of Copper-Doped Molybdenum Disulfide Counter Electrode and Its Application in Photovoltaic Devices
In dye-sensitized solar cells,Pt-free catalytic materials have been the focus of research.Copper-doped molybdenum disulfide films are grown direct on fluorine-doped tin oxide(FTO)conductive glass substrates by a one-step hydrothermal method and used as counter electrodes(CEs)for DSSCs.The results of cyclic voltammetry,electrochemical impedance spectroscopy and Tafel curves show that the copper-doped molybdenum disulfide films possess higher electrocatalytic activity than the pure MoS2 film.Therefore,the photo-voltaic conversion efficiency(PCE)of DSSCs based on copper-doped molybdenum disulfide film CEs is 4.73%,which is close to DSSCs based on Pt CEs(4.83%).
