This work addresses the challenge of current–voltage asymmetry in scalable laminated semitransparent organic photovoltaics (OPVs) for indoor applications. Vertical stratification of materials is shown to create an energy barrier, leading to performance differences under different illumination directions.

1D Light‐Emitting MAPbBr3 Perovskite Encapsulated in Carbon Nanotubes
Encapsulation of MAPbBr3 perovskite in single‐walled carbon nanotubes (SWCNTs) yields a hybrid nanomaterial with distinctive optoelectronic properties. Perovskite confinement induces a unified single‐peak photoluminescence (PL) with a reduced lifetime, while charge transfer alters the optical properties of nanotubes.

The side‐chain configuration in the bay region of C‐shaped ortho‐benzodipyrrole‐based non‐fullerene acceptors plays a crucial role in their self‐assembly, single‐crystal structures, and optoelectronic properties. The closely correlated molecular structure and performance underscore the importance of minimizing A–A self‐aggregation and enhancing D–A ...

Optical Whispering‐Gallery Mode as a Fingerprint of Magnetic Ordering in Van der Waals Layered CrSBr
A novel nanoscale optomagnetic sensing approach is developed using whispering‐gallery mode resonances in a self‐rolled‐up microcavity. This method enables ultra‐sensitive detection of weak magnetism by correlating resonance shifts with magnetic susceptibility.

The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...

Double Helical Plasmonic Antennas
Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.
