摘要：
Morphology plays a vital role in dye-sensitized solar cells (DSSCs) due to their high surface area, dye adsorption and electron transport. In this study, we have designed and fabricated titanate nanotube photoanodes by a simple one-step hydrothermal method. High-resolution transmission electron microscope (HRTEM) analysis revealed the transformation of nanoparticles to nanotube morphology. Brauner-Emmett-Teller (BET) method showed the enhanced surface area and pore diameter of nanotubes. TiO 2 nanotube photoanode showed excellent energy conversion efficiency (2.38 %), short circuit current densities (I sc ) (6.29 mA/cm 2 ), and fill factors (FF) (0.63), respectively.
