Unraveling the hysteretic behavior at double cations-double halides perovskite - electrode interfaces

Nano Energy, 2021
Abstract Despite over a decade of research on metal halide perovskites (MHPs) in the context of photovoltaic applications, understanding the nature of electronic and ionic processes associated with current-voltage (I-V) hysteretic behavior has been limited.

Entropy-Driven Stabilization of Multielement Halide Double-Perovskite Alloys

The Journal of Physical Chemistry Letters, 2022
Currently, a major obstacle restricting the commercial application of halide perovskites is their low thermodynamic stability. Herein, inspired by the high-stability high-entropy alloys, we theoretically investigated a variety of multielement double-perovskite alloys. First-principles calculations show that the entropy contribution to Gibbs free energy,

Lead‐Free Silver‐Bismuth Halide Double Perovskite Nanocrystals

Angewandte Chemie International Edition, 2018
AbstractLead‐free perovskite nanocrystals (NCs) were obtained mainly by substituting a Pb2+ cation with a divalent cation or substituting three Pb2+ cations with two trivalent cations. The substitution of two Pb2+ cations with one monovalent Ag+ and one trivalent Bi3+ cations was used to synthesize Cs2AgBiX6 (X=Cl, Br, I) double perovskite NCs.

Halide Double Perovskites: Insights into Structure, Defects, and Luminescence

ACS Applied Materials & Interfaces
Lead halide perovskites have turned out to be a promising class of materials due to their excellent photophysical and electronic transport properties. However, lead toxicity and weak operational stability of lead halide perovskites necessitate the search for environment-friendly perovskites that can serve as a good visible-light absorber or emitter ...

Recent Advances and Optoelectronic Applications of Lead‐Free Halide Double Perovskites

Chemistry – A European Journal, 2020
AbstractOrganic–inorganic metal halide perovskites (most notably CH3NH3PbI3) have demonstrated remarkable physical attributes for photovoltaic and diverse optoelectronic applications, whereas concerns about toxicity owing to the use of lead in the chemical composition still motivate further exploration of new, nontoxic candidates.
