Compared with the silicon solar cells and the dye sensitized solar cells, the quantum dot (QD) solar cells have the advantages of lower cost, better performance and wider applications, and one trend is to develop the all-solid-state QD solar cells with solid electrolytes. The key to the performance of solar cells lies in how to improve the electron transport of the photoelectrode and the filling of solid electrolytes. In this research, the two-step anodic oxidation method was utilized to prepare the TiO2 nanoarray as the ultrafast transmission channel for electrons, and CdS QDs were deposited on the nanoarrays by successive ionic layer adsorption and reaction process, followed by the formation of the core-shell QDs as the sensitizer with the ion replacement method. Then PEDOT, which acts as the transmission channel for holes, was prepared in the nanotubes by in-situ polymerization via the electrochemical process. The all-solid-state QD-sensitized TiO2 nanoarray solar cells were thus fabricated. Effects of the fabrication conditions for the core-shell QDs and PEDOTs were studied on the absorption properties, charge transfer and photoelectric conversion efficiency of the solar cells, and the mechanism for charge transfer and transport were revealed in the TiO2 nanoarrays/core-shell QDs/PEDOTs. This finding is of great scientific significance to the microstructure design and study of novel solar cells. |
