Summary: Mixed Sn-Pb halide perovskites are more stable and can be tuned to give narrower band gaps compared to all-Pb-containing counterparts. The crystal structure of CsSnxPb1-xBr3 evolves from orthorhombic to cubic as the tin content increases, leading to a decrease in the band gap. Solid-state NMR spectroscopy reveals complete disorder in the structure, with random distribution of octahedra throughout. Compounds prepared through different methods show variations in crystallinity and optical absorption properties.

Summary: In this study, the passivation effects of 2-MP and 2-MDEP on iodine vacancy MAPbI(3) were comprehensively investigated using density functional theory calculations and ab initio molecular dynamics simulations. It was found that 2-MDEP showed stronger adsorption and localized charges on Pb atoms, leading to improved activation barriers for ion migrations, structural stability, and restrained nonradiative recombination. Moreover, 2-MDEP exhibited more remarkable shielding effects against moisture compared to 2-MP.

Summary: The research on three-dimensional halide perovskites is limited by the choice of A-site cations. In this work, four new three-dimensional bromide perovskitoids incorporating linear organic diammonium cations are reported. These compounds exhibit similar electronic band structures and dynamic lattice characteristics to regular three-dimensional perovskites. Structures with smaller Pb-Br-Pb angles and larger octahedra distortion show broad photoluminescence at room temperature.

Summary: The study focuses on the development of efficient photothermal materials for solar thermal-energy conversion. Red phosphorus (RP) nanosheets with uniform, sub-micron size and abundant defects were prepared via a simple ball-milling method. The RP60, exhibiting the smallest particle size, nanosheet morphology, and defect-rich surface, demonstrated a high solar steam generation ef-ficiency of 74.1% and a stable water evaporation rate of 1.34 kg/m2 center dot h under simulated sunlight illumination. By incorporating plasmonic resonance-heating silver nanoparticles on the RP60, the solar steam generation efficiency was further improved to over 96.0% with a water evaporation rate of 1.75 kg/m2 center dot h.
