| 英文摘要 | A key point for constructing quantum dot-sensitized solar cells (QDSSCs) with high efficiency is to improve the utilization of sunlight. While various TiO2 morphologies such as nanoparticles, nanosheets, nanotubes and nanorods have been used as photoanodes of QDSSCs for improving cell performance, these investigations are generally focused on a single morphology of TiO2. Herein, a combined photoanode structure based on TiO2 nanoparticles and {001}-faceted TiO2 nanosheets have been designed, which exhibits improvement in cell performance. Owing to the strong light scattering and fast electron transfer ability of TiO2 nanosheets, an optimal power conversion efficiency of 4.98% with a short circuit current density (Jsc) of 17.57 mA cm 2, an open circuit voltage (Voc) of 0.63 V and a fill factor (FF) of 0.45 is achieved compared to the TiO2 nanoparticle photoanode (3.61%). The present work offers a feasible method towards improving the efficiency of QDSSCs. |
