Doping effects of transition metal elements to titanium dioxide for perovskite solar cells

Organic-inorganic hybrid heterojunction solar cells containing perovskite CH3NH3PbI3 using Nb, Ta, or V-doped TiO2 as electron-transporting layers were fabricated and characterized. By Nb doping, the conductivity and carrier density of the TiO2 increased, and its flat-band potential showed a positiv...
