Summary: The timescale of the orthorhombic-to-tetragonal phase transition in methylammonium lead triiodide (MAPbI3) was investigated using nanosecond transient absorption spectroscopy. A clean signature of transient, reversible orthorhombic-to-tetragonal transition was observed on the tens-of-nanoseconds timescale. Compared to inorganic phase-change materials, MAPbI3 exhibited orders-of-magnitude-slower phase transition, indicating a large energy barrier for activating the hydrogen-bond network and cooperative octahedral rotations. This approach provides insights into phase-transition dynamics in metal halide perovskites (MHPs) and other hybrid materials.

Summary: Recently, cesium bismuth halide perovskites have been considered as potential substitutes for cesium lead halide perovskites due to their low toxicity. However, the photophysics of cesium-bismuth halides nanocrystals (NCs) has not been fully understood due to the debated structures. This study successfully synthesized pure Cs3BiBr6 and Cs3Bi2Br9 NCs with controlled structures. The photophysical properties of the Cs3Bi2Br9 NCs were investigated, and their potential for optoelectronic applications was demonstrated.

Summary: We demonstrate that formamidinium-based crystals differ from methyl ammonium-based halide perovskite crystals due to the presence of intrinsic local static disorder in their inorganic sublattice, despite having a well-defined average crystal structure. Our study combines terahertz-range Raman scattering, single-crystal X-ray diffraction, and first-principles calculations to investigate the temperature-dependent dynamics of the inorganic sublattice in the range of 10-300 K. The temperature evolution of the Raman spectra reveals that low-temperature, local static disorder significantly influences the crystal structural dynamics and phase transitions at higher temperatures.

Summary: In this study, the popular donor material PM6 is used as a dopant-free hole transport layer (HTL) in CsPbI3 perovskite solar cells, replacing the commonly used Spiro-OMeTAD. This improves the performance of the PSCs by increasing the power conversion efficiency (PCE). The PSCs with PM6 as the HTL retain over 90% of the initial PCE after being stored in a nitrogen-filled environment for 3000 hours, while the PSCs with Spiro-OMeTAD as the HTL maintain approximately 80% of the initial PCE under the same conditions.

Summary: In this study, iron single atoms supported on a monolithic porous graphene film (Fe1-PGF) were employed as electrodes for catalyzing the VO2+/VO2+ redox couple. The Fe1-PGF electrode exhibited improved electrochemical performance compared to metalfree PGF and commercial graphite felt electrode due to the high intrinsic catalytic activity, superior surface hydrophilicity, enhanced mass transfer efficiency, and exposure of active sites. The single-cell battery assembled with Fe1-PGF showed a high voltage efficiency (77.96%) and energy efficiency (70.27%) at a current density of 60 mA cm-2, along with lower overpotential and higher rate capability. This study demonstrates the promising application of single atom catalysts (SACs) in catalyzing vanadium redox couples in VRFBs and encourages further exploration in other types of redox flow batteries.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.
