Hybrid Two‐Step Inkjet Printing and Dip‐Coating Enable Scalable 30%‐Efficient Perovskite/Silicon Tandem Solar Cells

Advanced Energy Materials, EarlyView.
Adopting a scalable hybrid two‐step deposition process route, textured perovskite/silicon tandem solar cells achieve over 30% power‐conversion efficiency. The process route replaces all non‐scalable spin‐coating steps, including organic precursor deposition, self‐assembled monolayer formation, and passivation layer deposition, with scalable techniques ...

Fluxional Monomers Remodel Crystallinity at Low Loadings in Diketopyrrolopyrrole Co‐Thienothiophene Conjugated Polymers

Angewandte Chemie, EarlyView.
Bullvalene is a fluxional molecule capable of adopting numerous conformations spontaneously; just like a Rubik's Cube. In this paper, we explore the incorporation of bullvalene into the backbone of a highly rigid conjugated polymer semiconductor and observe that the inherent fluxionality reduces average crystallite size.

Trash to Treasure: PFAS‐Functionalized MOFs for Boosted Piezocatalytic H2 Production

Advanced Energy Materials, EarlyView.
A novel pollutant‐as‐functional‐additive strategy is developed via postsynthetic modification of MOF‐808(Hf) with perfluorohexanoic acid (PFHxA), a typical PFAS pollutant. The modification boosts the dipole moment of the MOFs, enhances their piezoelectricity to promote efficient electron‐hole separation, thus delivering ultrahigh piezocatalytic ...

Engineering Polar Nanoregions in COFs via Controlled Symmetry Breaking Toward Piezocatalysis

Angewandte Chemie, EarlyView.
Polar nanoregions (PNRs) are engineered within covalent organic frameworks via asymmetric grafting of highly polar polyfluoroalkyl chains, which enables controlled symmetry breaking. These randomly oriented artificial PNRs dynamically respond to mechanical stimuli and impart relaxation behavior to the COFs (TFB‐TAPT‐FA).

From Data to Discovery: Machine Learning–Enabled Intelligent Characterization of Two‐Dimensional Materials

Advanced Intelligent Discovery, EarlyView.
Machine learning serves as a central engine for the intelligent characterization of two‐dimensional materials by integrating multimodal techniques, including optical microscopy, spectroscopy, electron microscopy, and scanning probe microscopy (SPM). This unified framework enables automated, high‐throughput, and quantitative extraction of structural ...

Suppressing Cathode Corrosion Induced by Impurity Cations in Alkaline Water Electrolyzers

Angewandte Chemie, EarlyView.
Impurity Fe species in electrolyte accelerate cathodic corrosion in alkaline electrolyzers by promoting peroxide formation. A strongly Lewis acidic CeOx protection layer stabilizes interfacial electronic structure via Fe−CeOx interactions, scavenges reactive oxygen species, and suppresses Fe accumulation, enabling stable Ni cathodes under universal ...
