Summary: The stereochemical expression of the 6s(2) lone pair on the lead atom affects the crystal structures and physical properties of lead halide perovskites. We report the synthesis and characterization of a 2D lead bromide hybrid with a rarely observed seven-coordination geometry, highlighting the strong stereo-active lone pair on the Pb2+ cation. Comparisons with other 2D perovskites demonstrate the influence of the lone pair expression on the coordination geometry and optical/electronic properties.

Summary: In this study, the phase separation of PEDOT and PSS chains in the film was controlled by ammonium carbamate (AC), resulting in a modified film with lower trap density and more facile carrier transport. As a result, tin halide perovskite solar cells (TPSCs) using the modified PEDOT:PSS film achieved a significantly improved short-circuit photocurrent (J(sc)), open-circuit voltage (V-oc), and power conversion efficiency (PCE).

Summary: In this work, polarized Raman spectroscopy is used to study the internal vibrations of the 3-cyanopyridinium cation in the halide post-perovskite (3cp)PbBr3. Vibrational frequencies and intensities of a single cation are calculated using density functional theory, and selection rules for cation vibrations in the crystal are established. These rules, along with modeling results, are used to identify the internal vibrations of the cation in the Raman spectrum of the crystal. Narrow and isolated internal vibrations of cations can be used as spectators of the crystalline environment.

Summary: A porous PbI2 layer with ordered array structure is successfully fabricated by integrating a succinamide (SA) additive with nanoimprinting technology, leading to omnidirectional diffusion and sufficient conversion to perovskites. The unencapsulated device achieves an efficiency of 23.56% and excellent long-term humidity stability. The perovskite solar cell and module achieve impressive efficiencies of 21.57% and 16.42%, respectively. This work paves the way for large-scale fabrication of high-performance perovskite photovoltaic devices.

Summary: Bismuth doping has effects on the crystal structure and phase transitions of the perovskite semiconductor MAPbBr(3). The phase transition temperature decreases and the number of phase transitions decreases with increasing Bi doping. X-ray diffraction shows that lattice constant decreases with Bi incorporation, suggesting dominant bismuth substitutional doping on the lead site.

Summary: This study investigates the charge dynamics at the semiconductor-liquid junction in copper bismuth oxide (CBO) photocathodes using various spectroelectrochemical experiments. The results show that the presence of surface states above the valence band of CBO leads to low charge transfer efficiency. This research provides new insights for the optimization of CBO-based photoelectrochemical systems.

Summary: Aluminum-doped SrTiO3 nanoparticles were synthesized with controllable aluminum doping by a mild hydrothermal method, and the photocatalytic overall water splitting was studied. The results showed an excellent photocatalytic performance with a H-2 production rate of about 4.1 mmol h(-1) g(-1) and an O-2 production rate of about 1.9 mmol h(-1) g(-1). This improvement in performance was attributed to the tuned surface band bending of SrTiO3 achieved by regulation of the Fermi level, which enhanced charge separation and accelerated the redox reaction.

Summary: The development of a universal strategy for designing photocatalysts with precise structure regulation is necessary to achieve efficient hydrogen production from water splitting. This study demonstrates the universality of a supramolecular precursor-based route for synthesizing ultrathin porous carbon nitride photocatalysts by incorporating various amino acids, enabling simultaneous production of H2 and H2O2 from pure water splitting. The improved photocatalytic performance is attributed to the molecular structure regulation of carbon nitride photocatalysts with aldehyde functional groups, which promotes adsorption/desorption processes and charge-carrier dynamics.
