Stability of the Halide Double Perovskite Cs2AgInBr6
The Journal of Physical Chemistry Letters, 2023 Cs2AgInBr6 is among the lead-free halide perovskites of interest, predicted by first-principles calculations to be stable with a direct band gap, but there has been only one report of its synthesis. Herein we report the formation of Cs2AgInBr6 thin films through thermal evaporation of CsBr, AgBr, and InBr3 and subsequent annealing between 130 °C and ...

Synthetic approaches for thin-film halide double perovskites [PDF]
Matter, 2021 Summary Inspired by the fascinating class of hybrid organic-inorganic halide perovskite materials, halide double perovskites have emerged as non-toxic Pb-free contenders for application as active layers in optoelectronic devices. Heterovalent substitution of Pb2+ by non-toxic metal cations yields the double-perovskite structure, which allows for ...

Halide Pb-Free Double–Perovskites: Ternary vs. Quaternary Stoichiometry [PDF]
Energies, 2020 In view of their applicability in optoelectronics, we review here the relevant structural, electronic, and optical features of the inorganic Pb-free halide perovskite class. In particular, after discussing the reasons that have motivated their introduction in opposition to their more widely investigated organic-inorganic counterparts, we highlight ...
