TiO₂ is a promising photoanode material with significant light conversion efficiency in dye-sensitized solar cells (DSSCs). However, the multidimensional TiO₂ nanostructures have a great impact on the production of highly efficient solar cells. Here, the hydrothermal method was assigned to synthesize TiO₂ nanoparticles (TNPs), TiO₂ nanorods (TNRs), and TiO₂ nanotubes (TNTs) for photoanodes. The crystallinity, surface and internal morphological changes were analyzed with X-ray diffraction, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The N719 dye as the light absorber and idolize as the electrolyte along with fabricated photoanode with different TiO₂ nanostructures for construction of DSSCs, among TNTs based DSSC showed the highest power conversion efficiency (PCE) of 5.03% compared to TNPs and TNRs.
