Structural Features and Optical Properties of All-Inorganic Zero-Dimensional Halides Cs₄PbBr_6-xI_x Obtained by Mechanochemistry.

ABSTRACT: Despite the great success of hybrid CH₃NH₃PbI₃ perovskite in photovoltaics, ascribed to its excellent optical absorption properties, its instability toward moisture is still an insurmountable drawback. All-inorganic perovskites are much less sensitive to humidity and have potential interest for solar cell applications. Alternative strategies have been developed to design novel materials with appealing properties, which include different topologies for the octahedral arrangements from three-dimensional (3D, e.g., CsPbBr₃ perovskite) or two-dimensional (2D, e.g., CsPb₂Br₅) to zero-dimensional (0D, i.e., without connection between octahedra), as the case of Cs₄PbX₆ (X = Br, I) halides.
