Collaborative Optimization of Charge Carrier Dynamics and Energy Loss of Organic Solar Cells via Rational Morphology Regulation

Aggregate, Volume 7, Issue 6, June 2026.
This work systematically investigates the effects of 3‐phenylthiophene (TPh), biphenyl (BPh), and 1‐chloro‐4‐iodobenzene (CIB) additive treatments on photoactive layer morphology. Among them, BPh synergistically enhances charge dynamics and significantly reduces energy loss, enabling simultaneous improvements in photocurrent and voltage and thus ...

Highly Efficient Short‐Wavelength Infrared OLEDs at 1000 nm via Phosphorescent‐Host Engineering

Aggregate, Volume 7, Issue 6, June 2026.
A phosphorescent‐host strategy enables efficient SWIR OLEDs by harvesting both singlet and triplet excitons. The devices reach a record EQE of 2.64% at 920 nm, efficient emission at 1000 nm is achieved with an external quantum efficiency (EQE) exceeding 0.22% and a radiance of 1805 mW sr−1 m−2, establishing a general host‐engineering approach for SWIR ...

Narrowband Macrocycles: A New Paradigm for High‐Color‐Purity Organic Light‐Emitting Diodes

FlexTech, Volume 2, Issue 1, Page 34-43, June 2026.
This graphical abstract illustrates two key strategies for constructing macrocyclic multi‐resonance (MR) emitters for high‐performance OLEDs: (1) the covalent assembly of MR moieties onto macrocyclic scaffolds, and (2) the local multi‐resonance strategy within the macrocyclic backbone.
