Phase Evolution Kinetics in Additive‐Free 19.75% Organic Photovoltaics Empowered by Solvent Vapor Annealing

Advanced Functional Materials, EarlyView.
Solvent vapor annealing enables kinetic control of additive‐free morphology in organic solar cells. Selective plasticization of acceptor forms an optimal fibrillar network, boosting efficiency to 19.06% (binary) and 19.75% (ternary), with ultrafast exciton dissociation and reduced recombination.

Unified Analytical Framework for Understanding the Operational Stability of Blue Phosphorescent OLEDs: Quantitative Insights Into Exciton Recycling and Bimolecular Interactions

Advanced Functional Materials, EarlyView.
Blue phosphorescent OLEDs remain limited by poor operational stability. Here, a unified analytical framework integrating transient photoluminescence and magneto‐electroluminescence is developed to correlate intrinsic material photophysics with electrically driven degradation.

Powering Nanocrystal‐Based Heat Engines With Light‐Emitting Metasurfaces That Influence Their Temperature

Advanced Functional Materials, EarlyView.
Metasurfaces and other structured photonic environments can dramatically modify the absorption and/or light emission of semiconductors. However, the consequences of these changes on the temperature of the system are not well understood. The authors address this problem for colloidal nanocrystals and leverage their findings to convert light into ...
