Abstract

Although tin oxide (SnO2) has been employed recently as an efficient electron-transporter to realize highly efficient organometal halide perovskite solar cells (PVSCs), it is still quite challenging to apply it through facile solution-based synthesis at low enough temperature (2 to achieve homogeneous and crystalline thin film as efficient electron-transporting layer for PVSCs. The fabricated SnO2 film not only has high transparency (from 350 nm to near-infrared region) but also possesses good electron extraction ability, as evidenced by the efficient PL quenching in bilayered SnO2/CH3NH3PbI3 film. By passivating SnO2 surface with a C60-containing self-assembled monolayer (C60-SAM), a high power conversion efficiency (PCEmax) of >15% with negligible hysteresis can be achieved in PVSC. This demonstrates the great potential of applying this dual-fuel combustion process to improve processability and charge-transporting properties of metal oxides for organic electronics applications.
