Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

open access: yesAdvanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Trifluoromethoxylated Electron Acceptor Enabling Ternary Organic Solar Cells with over 20% Power Conversion Efficiency

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT In this work, we introduce a trifluoromethoxy (OCF3) group as a pseudo‐halogen terminal group design for non‐fullerene acceptors, which combines strong inductive electron‐withdrawing ability with moderate resonance donation. The as‐synthesized BTP‐OCF3, when benchmarked against its methoxy analogue BTP‐OCH3, demonstrates narrowed bandgap ...

Meniscus Pixel Printing for Contact‐Lens Vision Sensing and Robotic Control

open access: yesAdvanced Functional Materials, EarlyView.
A visual‐sensing contact lens is enabled by meniscus pixel printing (MPP), which rapidly patterns a 200 µm perovskite photodetector pixel in 1 s without masks, vacuum processing, or bulky equipment. A deep‐learning‐based super‐resolution reconstructs sparse on‐lens signals into 80 × 80 high‐resolution visual information, while AI‐driven eye‐tracking ...
