Oriented one-dimensional TiO2 nanorod arrays (TNAs) thin film was grown on transparent conductive glass substrate by hydrothermal method. After calcination, TNAs exhibited a vertically standing structure, with average thickness of 1.21, 2.17 mu m and diameter of 274, 333 nm, respectively. Then the as-prepared TNAs were used as electrode to fabricated dye-sensitized solar cells (DSCs) with C106 sensitizer (Zhao et al., 2013) [17], and the kinetic parameters of electron transport in TNAs-electrode were investigated. Results showed that the TNAs-electrode DSCs exhibited longer electron lifetime and diffusion length than that based on TiO2 nanocrystals-electrode. (C) 2015 Elsevier B.V. All rights reserved.
