Metal Halide Hybrid Perovskites

Halide Perovskites have gained much attention in the past decade owing to their impressive optical and electrical properties like direct tunable bandgaps, strong light absorption, high photoluminescence quantum yield, and defect resistance shown by them. These materials find application in numerous fields including photovoltaics, optoelectronics, catalysis, and lasing applications. Multidimensional hybrid perovskites have been extensively researched as these structures lead to superior results. They combine the properties of three-dimensional variant along with the stability of the two-dimensional perovskite. This chapter focuses on the unique properties of metal halide perovskites including the crystal structure, optical, electronic, and electrical properties. The different techniques followed for the synthesis of metal-halide nanostructures and 2D/3D hybrids are also included focusing on the changes in physical properties and the structure of these materials.
