Conductive Tin Oxide Under the Thermal Budget of Perovskite/TOPCon Tandems: Toward Indium‐Free Contacts

open access: yesAdvanced Materials Technologies, EarlyView.
This work demonstrates that achieving conductive undoped SnOx contacts required careful tailoring of oxygen vacancy (VO) tuning and defect engineering. Controlling oxygen deposition pressure and low‐temperature annealing (300°C) optimizes defect stoichiometry and mitigates carrier scattering. This low thermal budget approach significantly enhances Hall

Intramolecular Direct Arylation Enables Access to Diverse Photophysical Properties for π‐Expanded 1,4‐Dihydropyrrolo[3,2‐b]pyrroles

open access: yesAdvanced Optical Materials, EarlyView.
The unique combination of photophysical properties for π‐expanded 1,4‐dihydropyrrolo[3,2‐b]pyrroles (DHPPs) can be reached via a new synthetic approach. π‐Expanded DHPPs possessing electron‐withdrawing functionalities with emission reaching 700 nm, as well as large double helical systems were prepared and investigated.

Crossover From Excitonic to Bulk Emission in Metal Halide Perovskite Nanocomposites

open access: yesAdvanced Optical Materials, EarlyView.
A transition from excitonic to free‐charge recombination is uncovered in perovskite nanocomposites as a function of nanostructure size using PLQY(R, F) mapping as a function of excitation fluence (F) and repetition rate (R). These findings demonstrate that PLQY(R, F) mapping serves as a powerful and non‐invasive tool to extract quantitative information

Breaking Optical Transparency and Electromagnetic Performance Trade‐Offs for Transparent Reflective Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
A theory‐guided magnetoelectric metasurface design breaks the conventional optical transparency and electromagnetic performance trade‐offs. By preserving the electric and magnetic current paths required for efficient reflection through fine‐metal‐line structure, the developed transparent reflective metasurface achieves high optical transparency without
