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.
