Fabrication of dye-sensitized solar cells with N-doped TiO2 thin films: Effect of the nitrogen doping on the photoexcitation processes and generation of electron acceptor states

Nowadays much efforts have been done with the aim to increase the global efficiency of the dye-sensitized solar cells so that the doping of the TiO2 structure have been suggested as one of the most interesting solutions. In this paper the effect of the nitrogen incorporation in the TiO2 structure and studies about the effect of the doped films on the general properties of the solar cells are conducted.
