Halide Mixing in CsAgBi(I Br ) Double Perovskites: A Pathway to Tunable Excitonic Properties.
J Phys Chem C Nanomater Interfaces
September 2024
Article Synopsis
- CsAgBiBr is a promising semiconductor but has limitations for solar cell use due to its indirect band gap and localized electronic structure.
- Recent research on CsAgBi(I, Br) nanocrystals shows that mixing halides significantly alters the electronic properties and optical excitations, enhancing exciton behavior.
- The study confirms that up to 11% iodide can be mixed into the bulk material using mechanosynthesis, leading to a red-shifted absorption that aligns with theoretical predictions.
A better understanding of the materials' fundamental physical processes is necessary to push hybrid perovskite photovoltaic devices towards their theoretical limits. The role of the perovskite grain boundaries is essential to optimise the system thoroughly. The influence of the perovskite grain size and crystal orientation on physical properties and their resulting photovoltaic performance is examined.

However, understanding their crucial elastic properties for synthesis and device operation remains limited. We performed temperature- and pressure-dependent synchrotron-based powder X-ray diffraction at low pressures (ambient to 0.

Method: The HIII-05F and THOR-05F were subjected to 3 different abdominal loading conditions: fixed-back belt pull (low compression), fixed-back belt pull (high compression), and free-back rigid bar impact at 6 m/s. The stroke of the impact was controlled to represent injurious and noninjurious loading conditions as observed in the experiments with postmortem human subjects (PMHS).
Objective: The purpose of this study was to generate biomechanical response corridors of the small female thorax during a frontal hub impact and evaluate scaled corridors that have been used to assess biofidelity of small female anthropomorphic test devices (ATDs) and human body models (HBMs).
Methods: Three small female postmortem human subjects (PMHS) were tested under identical conditions, in which the thorax was impacted using a 14.0 kg pneumatic impactor at an impact velocity of 4.
