Anatase titania nanotube (TNT) is prepared by two-steps hydrothermal growth method. Using the TNTs and titania particles (P25), a highly stable and uniform titania colloid without any sedimentation in 180 days is prepared by hydrothermal treatment. Based on the titania colloid, a flexible dye-sensitized solar cell (DSSC) is fabricated at low temperature. The influence of preparation conditions on the properties of TNTs and titania colloid is discussed by transmitting electron microscopy, scanning electron microscopy, selected area electron diffraction, X-ray diffraction, UV–vis absorption spectra, and Brunauer–Emmet–Teller surface area measurements. Under an optimized condition, a flexible DSSC with light-to-electric energy conversion efficiency of 4.0% is achieved under a simulated solar light irradiation of 100 mW cm−2 (AM 1.5).
