The successful development of organic-inorganic perovskite materials mainly based on CH3NH3PbI3 has improved the PCE of solar cells significantly and reduced the fabrication cost relatively. The majority of the researches focused on studying different ways of improving the performance and stability of perovskite devices with less attention paid to minimizing the time of fabrication. The reduction of fabrication time can simultaneously reduce the fabrication cost and boost the industrial manufacturing capability. In this work, we report a simple and rapid method of making CH3NH3PbI3 layer at ambient laboratory conditions and applying it for advancing the photon-to-electricity conversion efficiency of liquid-state CuO-based perovskite-sensitized solar cells. The whole fabrication process starting from electrodepositing CuO to sandwiching counter electrode entails less than 10 min and the device efficiency reaches up to 0.35% under one sun illumination. |
