- Abstract
Single-crystalline anatase TiO2 nanorods (TiO2-SANRs) were synthesized through a facile solvothermal method and successfully applied as the photoanodes for efficient dyesensitized solar cells (DSCs). The prepared samples were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD). The power conversion efficiencies of TiO2-SANRs decorated Degussa P25 nanoparticle solar cells increased by 13.5 % compared with commercial Degussa P25 TiO2 solar cells unde standard illumination conditions (AM 1.5G, 100 mW/cm-2). The improved performance of the TiO2-SANRs decorated Degussa P25 nanoparticle solar cells was primarily ascribed to the enhanced short-circuit photocurrent density (Jsc) despite a declined dye-loading capacity The light-scattering effect in the long-wavelength region, as evidenced from the incident photon-to-current conversion efficiency (IPCE) response and the diffuse reflectance spectroscopy was recognized as the main reason for the photocurrent enrichment.
