Abstract

<p>Titania nano tube was successfully obtained by hydrothermal treatment of nano size TiO<sub>2</sub> fine powder in 10 M NaOH solution for 20 h at 110°C. The morphology of product was 8-10 nm in width and about 100 nm in length with tubular shape. The specific surface area was 270 m<sup>2</sup> g<sup>−1</sup>, much higher than that of starting material titania powder with 50 m<sup>2</sup> g<sup>−1</sup>. Photovoltaic properties of these titania film was also examined. The results were V<sub>OC</sub> = 0.704, I<sub>SC</sub> = 1.26 mA, η = 2.9%, FF = 0.66 for titania nano tube, and V<sub>OC</sub> = 0.767, I<sub>SC</sub> = 1.20 mA, η = 3.0%, FF = 0.72 for titania nano powder (P-25).</p>
