| 英文摘要 | a hierarchical configuration of tio2 nanoarray film, comprising a nestlike tio2 nanoarray layer integrated with a nanosheet network overlayer, was constructed. the hierarchical tio2 film was obtained by the post-hydrothermal treatment with naoh solution on hydrothermally synthesized tio2-derived nanostructured arrays grown on fluorine-doped tin oxide substrate (fto). the tio2 films were characterized by field-emission scanning electron microscope (fe-sem), x-ray diffraction (xrd), ultraviolet-visible (uv-vis) diffuse reflectance spectroscopy, and absorbance spectroscopy. fe-sem shows that the hierarchical tio2 film with a thickness of 1.5 mu m is composed of a nanosheet overlayer (similar to 0.2 mu m height) and the nestlike nanoarray layer (similar to 1.3 mu m height). xrd patterns display that the tio2 films have pure anatase phase structure. uv-vis spectra reveal enhanced light scattering and dye adsorption ability of the hierarchical tio2 film. for the dye-sensitized solar cell (dssc) based on the nanosheet/nestlike nanoarray hierarchical tio2 film, a short-circuit current (j(sc)) of 7.79 ma.cm(-2), open-circuit voltage (v-oc) of 0.80 v, fill factor (ff) of 0.40, and photoelectric conversion efficiency (eta) of 2.48% are achieved. within the dye-sensitized solar cell, the photoelectric conversion efficiency of the hierarchical tio2 film was nearly ten times higher than that of nanostructured array film. |
