| 摘 要： | 通过硫化介孔Cu_2O微球得到花状Cu_xS纳米催化材料,并采用丝网印刷法制备出Cu_xS/FTO对电极。通过X射线衍射(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)等表征手段对所得材料的结构和形貌进行了探究,同时系统考察了溶液浓度、硫化时间、催化剂印刷层数对Cu_xS/FTO电极的催化性能影响和所组装量子点敏化太阳电池的光电转换效率,其中基于Zn-Cu-In-Se量子点敏化的电池转换效率达8.80%,表现出花状Cu_xS优异的光电催化性能。

| 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%. |
