摘要

TiO₂ nanoparticles can be applied to improve the efficiency of photo electrode materials used in dye solar cells (DSSC). This research investigated how to form the porous thin layer of TiO₂ nanoparticles on FTO (F-doped SnO₂) substrate using a water-based TiO₂ nanofluid. The 100 nm TiO₂ nanoparticles with bundle-shaped morphology were produced to investigate photo-electrode properties in dye-sensitized solar cells. It was found that the TiO₂ nanoparticles can be dispersed uniformly into deionized water. A layer of nanofluid was deposited on the FTO substrate, using spin coating method and then sintering was carried out to join the TiO₂ crystals and form a thin porous layer of TiO₂ particles on the substrate. We demonstrated that sintering plays a key role on 3D morphologies and porosity of deposited TiO₂ nanoparticles in the films.
