| Abstract: A simple method for preparing flower-like CuxS nanomaterials by sulfidation of pre-prepared mesoporous Cu2O microspheres was reported. CuxS/FTO counter electrodes were further obtained via screen printing technique. X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were employed to characterize the structure and morphology of the prepared materials, and the influences of the layers of CuxS, solution concentration and sulfidation time on the electrochemically catalytic activity of counter electrodes as well as the conversion efficiency of the assembled quantum dot sensitized solar cells were also investigated. Results showed that the flower-like CuxS had excellent catalytic activity and Zn-Cu-In-Se based quantum dot sensitized solar cells had good performance with conversion efficiency as high as 8.80%. |
