Origin of Ferroelectricity in Two Prototypical Hybrid Organic–Inorganic Perovskites

Journal of the American Chemical Society, 2022
Hybrid organic-inorganic perovskite (HOIP) ferroelectrics are attracting considerable interest because of their high performance, ease of synthesis, and lightweight. However, the intrinsic thermodynamic origins of their ferroelectric transitions remain insufficiently understood.

Organic-Inorganic Hybrid Perovskites

2018
The dielectric functions and optical constants of various organic-inorganic hybrid perovskite semiconductors, including HC(NH2)2PbI3, CH3NH3PbI3, CH3NH3PbBr3 and CH3NH3PbCl3, are summarized. For CH3NH3Pb(I, Br)3 alloys, the variation of the dielectric function with Br content, calculated by applying the energy shift model, is presented.

Metal-Free Hybrid Organic–Inorganic Perovskites for Photovoltaics

The Journal of Physical Chemistry Letters, 2020
There has been intense interest in hybrid organic-inorganic perovskites (HOIPs) in the materials science community due to their unexpected and fascinating properties with respect to photovoltaic applications. The intrinsic toxicity of Pb-based HOIPs, however, seriously hinders its practical large-scale commercialization.

Organic–Inorganic Hybrid Perovskite Nanowire Laser Arrays

ACS Nano, 2017
Fabrication of semiconductor nanowire laser arrays is very challenging, owing to difficulties in direct monolithic growth and patterning of III-V semiconductors on silicon substrates. Recently, methylammonium lead halide perovskites (MAPbX3, X = Cl, Br, I) have emerged as an important class of high-performance solution-processed optoelectronic ...

Hydrogen Bonding and Stability of Hybrid Organic–Inorganic Perovskites

ChemSusChem, 2016
AbstractIn the past few years, the efficiency of solar cells based on hybrid organic–inorganic perovskites has exceeded the level needed for commercialization. However, existing perovskites solar cells (PSCs) suffer from several intrinsic instabilities, which prevent them from reaching industrial maturity, and stabilizing PSCs has become a critically ...
