Highly crystalline titania nanorods were prepared from H2Ti3O7 nanotubes precursor and then used as the photoanode for indoline dyes sensitized solar cells. The cells sensitized by D131, D102 and D149 dyes exhibited the efficiencies of 4.63%, 4.56% and 5.47%, respectively. Interestingly, the photovoltaic properties can be enhanced significantly when the mixed dye was used as a sensitizer. The best efficiency of 7.30% was obtained using the mixed dye of D131 and D149 as a sensitizer. This result might be ascribed to the increased light-harvesting, prolonged electron lifetime and inhibited interfacial charge recombination. (C) 2013 Elsevier Ltd. All rights reserved.
