Abstract Mechanochemical synthesis has recently emerged as a promising route for the of functional lead halide perovskites well other (lead‐free) metal halides. presents several advantages with regards to more commonly used solution‐based processes such an inherent lower toxicity by avoiding organic solvents and finer control over stoichiometry final products. The ease implementation, either through use simple mortar pestle or electrically powered ball‐mill, low amount side products make...

Solvent-free mechanochemical synthesis of phase-pure inorganic halide perovskites is investigated in depth revealing several beneficial and detrimental effects ball-milling.
Phase‐pure CsSnI 3 , FASnI Cs(PbSn)I FA(PbSn)I perovskites (FA = formamidinium HC(NH 2 ) + as well the analogous so‐called vacancy‐ordered double Cs SnI 6 and FA are mechanochemically synthesized. The addition of SnF is found to be crucial for synthesis Cs‐containing but unnecessary hybrid ones. All compounds show an absorption onset in near‐infrared (NIR) region, which makes them especially relevant photovoltaic applications. Pb(II) improve electronic properties 3D Sn(II)‐based perovskites,...
We have synthesized fifteen inorganic and hybrid organic–inorganic non-toxic A<sub>3</sub>Bi<sub>2</sub>X<sub>9</sub> compounds (A = K<sup>+</sup>, Rb<sup>+</sup>, Cs<sup>+</sup>, CH<sub>3</sub>NH<sub>3</sub><sup>+</sup> HC(NH<sub>2</sub>)<sub>2</sub><sup>+</sup>; X I<sup>−</sup>, Br<sup>−</sup>, Cl<sup>−</sup>) through dry mechanochemistry.
Potassium halides (KX; X = I, Br, or Cl) were incorporated as partial replacements of CsBr in the mechanosynthesis CsPbBr3. This led to substitution both monovalent ions forming mixed Cs1-x K x PbBr3-y y perovskites. Longer photoluminescence lifetimes also observed, possibly linked formation a non-perovskite KPb2X5 passivating layer.
Abstract Herein the mechanochemical synthesis of inorganic as well hybrid organic–inorganic monohalide perovskites with tunable bandgaps is reported. It shown that bandgap bowing known for iodide mixed Sn–Pb also present in pure bromide analogous. This results technologically very interesting materials range 1.7–1.9 eV. Similar are typically achieved by mixing two halides prone to segregate over time. limits achievable open circuit voltage. For this problem eliminated, making these...
Abstract This work reports on the first thin‐film solid nanocomposite electrolyte (NCE) for lithium‐ion batteries made by combining two gas‐phase deposition techniques, molecular layer (MLD) and atomic (ALD). The advantage of using these techniques fabrication NCEs comes from ease integration in possibility to alter properties oxide matrix Li‐compound independently. Moreover, mesoporous based an MLD etching process, provides uniform interfaces with continuous conduction paths. An enhancement...
