TL;DR: In this article, a hybrid double perovskite, (MA)2AgBiBr6, was synthesized with a low band gap of 2.02 eV.
Journal ArticleDOI
The synthesis, structure and electronic properties of a lead-free hybrid inorganic–organic double perovskite (MA)2KBiCl6 (MA = methylammonium)
Fengxia Wei,Zeyu Deng,Shijing Sun,Fei Xie,Gregor Kieslich,Donald M. Evans,Michael A. Carpenter,Paul D. Bristowe,Anthony K. Cheetham +8 more
TL;DR: In this article, a hybrid double perovskite, (MA)2KBiCl6, which shows strong similarities to the lead analogues, was proposed for photovoltaic applications.
Journal ArticleDOI
Resolving the Physical Origin of Octahedral Tilting in Halide Perovskites
Jung-Hoon Lee,Nicholas C. Bristowe,June Ho Lee,Sung-Hoon Lee,Paul D. Bristowe,Anthony K. Cheetham,Hyun M. Jang +6 more
TL;DR: In this paper, the authors re-examine the origin of octahedral tilts in halide perovskites from systematic first-principles calculations and find that while steric effects dominate the tilt magnitude in inorganic halides, hydrogen bonding between an organic A-cation and the halide frame plays a significant role in hybrids.
Journal ArticleDOI
Exploring the properties of lead-free hybrid double perovskites using a combined computational-experimental approach
TL;DR: In this paper, a density functional theory screening of the hybrid double perovskites (MA)2BIBiX6 (BI = K, Cu, Ag, Tl; X = Cl, Br, I) showed that systems with band gaps similar to those of the MAPbX3 lead compounds can be expected.
Journal ArticleDOI
Role of hydrogen-bonding and its interplay with octahedral tilting in CH3NH3PbI3
TL;DR: First principles calculations on the hybrid perovskite CH3NH3PbI3 predict strong hydrogen-bonding which influences the structure and dynamics of the methylammonium cation and reveal its interaction with the tilting of the PbI6 octahedra.
