Mg-doped SnO2 with an ultrathin TiO2 coating layer was successfully synthesized through a facile nanoengineering art. Mg-doping and TiO2-coating constructed functionally multi-interfaced SnO2 photoanode for blocking charge recombination and enhancing charge transfer in dye-sensitized solar cells (DSC). The designed nanostructure might play a synergistic effect on the reducing recombination and prolonging the lifetime in DSC device. Consequently, a maximum power conversion efficiency of 4.15% was obtained for solar cells fabricated with the SnO2-based photoelectrode, exhibiting beyond 5-fold improvement in comparison with pure SnO2 nanomterials photoelectrode DSC (0.85%).
