Here we report that organo-lead halide perovskite CH3NH3PbI(3−x)Clx solution can be used as a new liquid electrolyte in dye-sensitized solar cells (DSCs). We find that the presence of inorganic octahedra of [PbX6]4− (X = I or Cl, or a combination of them) in this perovskite solution can not only remarkably improve the device stability but also enhance the photo-response of DSCs.
