Abstract
Currently, lead halide perovskite materials involving organic-inorganic hybrids and all-inorganic ones have attached more and more attention for their adhibition in photovoltaic devices, because of the unique properties like high light absorption coefficient, tunable bandgap, long carrier lifetime, and carrier diffusion length. In addition, it can be clearly seen that perovskite materials have unusual magnetic properties and excellent electronic properties. Herein, the structure of B-site substituted perovskite oxides are reviewed, and magnetic properties of A2BʹB″X6 are controlled by modifying their cations, such as magnetic order, leading to a wide range of possibly and interesting useful new materials. We review the perovskite manganite with a strongly correlative electronic system, and the strong interactions within electron results in sophisticated electronic properties and magnetic properties. Electronic structure and unique characteristics of halide perovskites such as the special Pb orbit and the grain boundaries of electrically benign are surveyed. What’s more, the suitable and excellent optical properties of kinds of perovskites with mixed compounds for solar cells, light-emitting diodes, and other applications are addressed.
