#$%^&*AU2020101018A420200723.pdf#####Abstract This invention discloses a ferroelectric/TiO2nanocrystalline composite film, its preparation method and application in sensitized solar cells. The preparation method disclosed by this invention is simple and has a low cost. It takes the prepared ferroelectric/TiO2nanocrystalline composite films as the photoanodes, and introduces the electric field generated by the ferroelectric dipoles into the photoanode film, which can effectively separate the photogenerated electron-hole pairs, reduce the interface charge recombination effect, enhance the activity and lifetime of electrons, and thus improve the photoelectric conversion efficiency of sensitized solar cells.Drawings of Descriptions F TO-coated Glass Figure 1 12~10 00wI 42 0 0.0 0.2 0.4 0.6 0.8 Voltage(V) Figure 2 1/2
