SINTERING EFFECTS OF BUNDLE-SHAPED TITANIUM OXIDE NANOFLUIDS ON THE PERFORMANCE OF DYE-SENSITIZED SOLAR CELLS
This paper is focused on manufacturing of semiconductor nanorod-TiO2 film for dye-sensitized solar cell applications. In order to create effective TiO2/dye/electrolyte interfaces for the newly developed photoelectrode, it is necessary to investigate how to control 3D morphology of the porous TiO2 layers on FTO substrate via thermal sintering of a water-based TiO2 nanofluid consisting of bundle-shaped TiO2 particles. The TiO2 nanoparticles were deposited on FTO glass substrate, using spin coater. The nanoparticles were reshaped to 1D nanorod morphology and fused to enhance the electron collection efficiency of TiO2 photoanode. The mixture of bundle-shaped TiO2 and spherical-TiO2 nanoparticles was sintered thermally to (a) fuse the TiO2 nanoparticles together, (b) systematically change their assembly process by changing the sintering profiles.
