Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Role of Intrinsic Electron Trapping in Negative Charging of Amorphous Alumina

Advanced Functional Materials, EarlyView.
Intrinsic electron trapping in amorphous Al2O3 is examined using hybrid‐DFT models spanning a wide density range. Both spontaneous and thermally activated trapping are identified, with pronounced spontaneous localization in dense, partly crystallized structures.

Interfacial Modulation for High‐Efficiency Large‐Area Organic Photovoltaics and Perovskite‐Organic Tandem Solar Modules

Advanced Functional Materials, EarlyView.
Self‐assembled monolayers (SAMs) are promising hole‐transporting materials for organic photovoltaics (OPVs), but suffer from self‐aggregation and poor large‐area uniformity. We find that interfacial modification using nicotinic hydrazide can eliminate the residual SAM aggregates by forming energetically favorable complexes, yielding uniform SAM.
