Stepwise Pre‐Treatment Enables Tunable Phase Evolution for High‐Efficiency Co‐Evaporated and Sulfurized Cu2ZnSnS4 Solar Cells

open access: yesSusMat, EarlyView.
A stepwise pre‐treatment strategy combining pre‐alloying and pre‐sulfurization regulates the phase‐evolution kinetics of co‐evaporated CZTS absorbers. The engineered intermediate phases promote direct kesterite crystallization, suppress defects and nonradiative recombination, and deliver a power conversion efficiency of 10.62%, representing the highest

Bi[IrBi6I12], Ag3[IrBi6I12], and BixCu3–3x[IrBi6I12]: Rock‐Salt Superstructures Based on Heavy‐Atom Clusters

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
New iridium‐containing bismuth subiodides based on cuboctahedral [IrBi6I12]3− clusters adopt chain‐like or rock‐salt‐related structure variants depending on the counter‐cations. Ag3[IrBi6I12] combines silver mobility at room temperature with long‐range ordering at low temperature, while DFT calculations reveal semiconducting behavior.

Sr2[CN2][NH] – A Carbodiimide Imide

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The mixed anion compound Sr2[CN2][NH] contains carbodiimide anions alongside imide anions and shares structural similarities with the respective quasi‐binary compounds. The novel mixed anionic compound Sr2[CN2][NH] crystallizes as colorless transparent platelets in the orthorhombic space group Pnma.

A femtosecond time‐resolved Bragg coherent diffraction imaging experimental setup at PAL‐XFEL for nanoscale lattice dynamics studies

open access: yesJournal of Synchrotron Radiation, EarlyView.
The XSS beamline at PAL‐XFEL provides a femtosecond time‐resolved Bragg coherent X‐ray diffraction imaging setup, optimized for tracking transient lattice dynamics and nanoscale strain fields within single crystals during dynamic processes.We report on the design and operational characterization of a femtosecond time‐resolved Bragg coherent X‐ray ...

Fast scanning chip calorimetry coupled with synchrotron SAXS: an easy‐to‐use plug‐in setup for standard SAXS beamlines

open access: yesJournal of Synchrotron Radiation, EarlyView.
The custom in situ fast scanning chip calorimetry–small‐angle X‐ray scattering (SAXS) setup developed in this work enables synchronized calorimetric measurements and continuous SAXS acquisition with millisecond time resolution during ultrafast thermal protocols.
