    • Abstract

       

      In this study, different titanium dioxide (TiO$_2$) nanostructures and phase were investigated as photoanode film for application in dye-sensitized solar cells. Rutile TiO$_2$ nanorods (NRs)-nanotrees (NTs) and TiO$_2$ NRs-microcauliflowers (MCFs) were synthesized via hydrothermal method for different time. The mixed phase of rutile-anatase film was fabricatedby applying TiO$_2$ nanoparticles paste on the synthesized TiO$_2$ NRs-NTs via squeegee method. The counter electrode film wasfabricated by spraying deposition and sputtering methods of reduced graphene oxide–multi-walled carbon nanotubes and platinum, respectively. Solar simulator measurement revealed that higher energy conversion efficiency (1.420%) and shortcircuit current density (3.584 mA cm$^{-2}$) were achieved by using rutile TiO$_2$ NRs-MCFs film. The utilization of a thick rutilefilm with microparticle structures increases dye adsorption, and thus enhances the electron excitation.
