英文摘要	Chinese Scholarship Council; Georgia Institute of Technology; National Natural Science Foundation of China [51072170, 21021002]; National Basic Research Program of China [2012CB932900]; Academic New Artist Ministry of Education Doctoral Post Graduate of China; Dye-sensitized solar cells (DSSCs) based on hierarchical rutile TiO2 flower clusters prepared by a facile, one-pot hydrothermal process exhibit a high efficiency. Complex yet appealing rutile TiO2 flower films are, for the first time, directly hydrothermally grown on a transparent conducting fluorine-doped tin oxide (FTO) substrate. The thickness and density of as-grown flower clusters can be readily tuned by tailoring growth parameters, such as growth time, the addition of cations of different valence and size, initial concentrations of precursor and cation, growth temperature, and acidity. Notably, the small lattice mismatch between the FTO substrate and rutile TiO2 renders the epitaxial growth of a compact rutile TiO2 layer on the FTO glass. Intriguingly, these TiO2 flower clusters can then be exploited as photoanodes to produce DSSCs, yielding a power conversion efficiency of 2.94% despite their rutile nature, which is further increased to 4.07% upon the TiCl4 treatment.
