Perovskite solar cells with the formula FA1-xCsxPbI3, where FA is formamidinium, provide an attractive option for integrating high efficiency, durable stability and compatibility scaled-up fabrication. Despite incorporation of Cs cations, which could potentially enable a perfect perovskite lattice1,2, compositional inhomogeneity caused by A-site cation segregation likely to be detrimental photovoltaic performance cells3,4. Here we visualized out-of-plane along vertical direction across films...
By substituting the oxygen evolution reaction (OER) with anodic urea oxidation (UOR), it not only reduces energy consumption for green hydrogen generation but also allows purification of urea-rich wastewater. Spin engineering d orbital and oxygen-containing adsorbates has been recognized as an effective pathway enhancing performance electrocatalysts.

Abstract Structural isomerism of colloidal semiconductor nanocrystals has been largely unexplored. Here, we report one pair structural isomers identified for which exhibit thermally-induced reversible transformations behaving like molecular isomerization. The two are CdS magic-size clusters with sharp absorption peaks at 311 and 322 nm. They have identical cluster masses, but slightly different structures. Furthermore, their interconversions follow first-order unimolecular reaction kinetics....
