Abstract

We have succeeded in preparing TiO₂ film at low-temperature using a binder-free paste and a process of low-temperature crystallization of anatase formed from hydrolysis of TiCl₄ at 150 °C. The electron diffusion coefficient of the chemically assisted sintered dye-sensitized solar cell (DSSC) was 3 times larger at the 1 × 10¹⁷ photons flux than that of non-sintered one. This is thought to be ascribed from the formation of inter-connecting TiO₂ between the TiO₂ nanoparticles by chemically assisted sintering process.
