Advances and Promises of Layered Halide Hybrid Perovskite Semiconductors

Abstract : Layered halide hybrid organic-inorganic perovskites (HOP) have been the subject of intense investigation before the rise of 3-dimensional (3D) HOP and their impressive performance in solar cells. Recently, layered HOP have also been proposed as attractive alternatives for photostable solar cells, and revisited for light emitting devices. In this review, we combine classical solid-state physics concepts with simulation tools based on density functional theory (DFT) to overview the main features of the optoelectronic properties of layered HOP. A detailed comparison between layered and 3D HOP is performed to highlight differences and similarities. In the same way as the cubic phase was established for 3D HOP, here we introduce the tetragonal phase with D4h symmetry as the reference phase for 2D monolayered HOP. It allows for detailed analysis of the spin-orbit coupling effects and structural transitions with corresponding electronic band folding. We further investigate the effects of octahedral tilting on the band-gap, loss of inversion symmetry and possible Rashba effect, quantum confinement and dielectric confinement related to the organic barrier, up to excitonic properties. Altogether this paper aims to provide an interpretive and predictive framework for 3D and 2D layered HOP optoelectronic properties.
