In order to reveal the electron transportation mechanisms of the oxide films in the perovskite solar cells, the hetero-junction and mesoscopic perovskite solar cells are prepared on flexible PI substrate, which are based on the ideas of matching the conductive bands, and differentiating the contact areas between the oxide films and the peorskite coatings. The influence of the structures (crystal lattices and optical band gap, conductive bands ) of the oxide films and perovskite coatings, as well as the contact area between them on the electron transition, transportation are investigated by measuring and calculating of the lattice structures, conductive bands, optical band gaps, the optical and electrical properties of the films, and the I-V properties of the perovskite solar cells. The possible electron transportation mechanisms of the oxide films in the perovskite solar cells, e.g. 1) pn heterojuncion, 2) or pin heterojuncion, 3) or the sensitizing effect to hold and transport the electrons from the absorb layers to the electrodes, are analyzed and discussed. This study will provide the experimental and theoretical data to help the fabrication of the high-effective flexible perovskite solar cells in the near future.
