Hybrid organic-inorganic perovskite materials have attracted enormous interest in recent years since they have demonstrated to be excellent candidates for thin film photovoltaics. This is mainly due to their extremely high absorption coefficients and to their capability to be processable through low temperature solution techniques.[1-3] Not only the intrinsic polycrystalline nature of the active layer, but also the properties of different conjugated polymers are going to determine the charge transport and recombination dynamics processes for the different cell architectures proposed. Herein, we present a planar heterojunction perovskite solar cell and study the effect of different conjugated polymers acting as hole transporting materials on the device performance. Power conversion efficiencies greater than 14% were attained after a careful optimization of the cell configuration, corresponding to one of the highest values reported in the literature for similar architectures.
