When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

Advanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

A Super‐Adhesive Air Filter With Capillarity‐Mediated Spontaneous Particle Absorption via Dynamic Bond Exchange

Advanced Materials, EarlyView.
We address the inherently weak particle adhesion of conventional air filters by coating a dynamically crosslinked adhesive layer that delivers capillarity‐driven strong adhesion and particle absorption mediated by dynamic bond exchange. The resulting enhancement in particle adhesion enables efficient ultrafast (up to 20 m s−1) and omnidirectional ...

Advanced Separators for Liquid and Quasi‐Solid Lithium Rechargeable Batteries: Design and Development

Advanced Materials, EarlyView.
This review traces the evolution of lithium‐ion battery separators from passive barriers to multifunctional components central to cell safety and performance. Polymer‐ceramic hybrids, nanofiber architectures, and bio‐derived membranes deliver ionic conductivities above 3 mS cm−1, thermal stability beyond 200 °C, and effective suppression of lithium ...
