Two kinds of CuS counter electrodes with different morphologies applied to QDSC were prepared by a solvothermal method and an in-situ method, respectively. The prepared counter electrodes were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, electrochemical impedance spectroscopy (EIS) and current-voltage (J-V) curve measurement, respectively. According to the results by morphology analysis, CuS nanoparticles with a size of 20 nm can be agglomerated into larger and irregular particles in CuS counter electrode prepared by the in-situ method, and CuS counter electrode prepared by the solvothermal method consists of nanorods and nanoparticles in microstructrue. The results reveal that two kinds of CuS counter electrodes are superior to Pt counter electrode in the electrical performance. CuS counter electrode prepared by the in-situ method yields the maximum power conversion efficiency (i.e., 1.840%) and the charge transfer resistance Rct is 3.346 Ω. CuS counter electrode prepared by the solvothermal method yields a power conversion efficiency of 1.450% and Rct is 2.609 Ω. The corresponding parameters of Pt counter electrode are 0.940% and 11.680 Ω, respectively.
