Dry‑Contact Trimming for All‑Perovskite Tandem Solar Cells via Solid‑Solution Homogenization
Advanced Energy Materials, EarlyView.Narrow‐bandgap Sn–Pb perovskites are promising bottom absorbers for all‐perovskite tandems but suffer from Sn‐rich surfaces and depth‐dependent lattice/compositional inhomogeneity. Layered‐perovskite‐assisted dry‐contact trimming removes Sn‐rich surface species and reconfigures the Sn–Pb absorber, enabling efficient charge collection, reduced voltage ...

Advanced Energy Materials, EarlyView.Operando SECM decouples hydrogen evolution from other degradation pathways in Zn metal batteries by quantifying its contribution during Zn electrodeposition. Although HER is shown to account for only a minor fraction of the irreversible charge loss, it remains a key indicator of interfacial evolution and by‐product formation governing cycling ...

Low‐Threshold Red Lasing in Diketopyrrolopyrrole‐Based Organic Semiconductor Films
Angewandte Chemie International Edition, EarlyView.Low‐threshold organic semiconductor lasers (OSLs) in the red region are achieved using diketopyrrolopyrrole (DPP) derivatives (DPA‐DPPMe and HMAT‐d‐DPP). Molecular design enables precise control of radiative‐decay and molecular orientation, suppressing optical losses and enhancing gain.

Self‐Assembled Telecom Color Centers in Silicon and Their Growth Environment
Advanced Physics Research, EarlyView.Influence of the growth pressure during the formation of self‐assembled color centers in silicon grown by molecular beam epitaxy at ultra‐low temperatures on the color center's photoluminescence spectral signature. The growth pressure crucially determines color center selectivity, as evidenced by G‐centers, W‐centers, and T‐centers, matrix purity, and ...

Strain‐Tunable Photoluminescence From Ge Quantum Dots on Si Nanotips for CMOS‐Compatible Photonics
Advanced Physics Research, EarlyView.This work studies strain in Ge quantum dots grown on Si nanotips using photoluminescence, X‐ray diffraction, and band structure calculations. It shows how emission changes with dot size, evaluates strain in the dot and substrate, and explains the role of direct and indirect transitions in the optical behavior.
