A binder‐free nanocrystalline TiO 2 paste with high viscosity (see Figure) has been developed using non‐thermal sintering conditions to deposit a TiO 2 film with good interparticle connectivity. A dye‐sensitized TiO 2 film dried at 150 °C demonstrates an overall conversion efficiency of 3.52 % under AM 1.5 (1000 W m –2 ) illumination. The binder‐free TiO 2 paste is expected to be utilizable in flexible dye‐sensitized solar cells.
