Photoanodes for flexible DSSC have been prepared through a chemical sintering method using hydrothermal cement at low temperature of 120°C. The addition of the hydrothermal cement can effectively increase the adhesion between the photoanode and flexible ITO ‐ PET substrate and build the interconnection between nanoparticles at low temperature for the fast transport of electrons. The flexible DSSC based on the photoanode obtains a relatively high photo‐to‐electric conversion efficiency of 4.0%. The method basing on the commercially available TiO 2 with a small proportion of hydrothermal cement is suitable for roll‐to‐roll screen‐printing preparation, which is expected to be scaled up for mass production of high performance flexible DSSC s.
