Self‐Cleaning Sensor Surfaces for Long‐Term Environmental Monitoring

open access: yesAdvanced Engineering Materials, EarlyView.
Long‐term use of unattended outdoor sensors without soiling or biofouling is achieved through generation of a micro‐ and nanorough cuvette surface by combing hydrophobic nanoparticles with fluorinated polymers, crosslinked and surface‐attached through CHic chemistry. The coating demonstrates self‐cleaning behavior and prolonged outdoor stability, which

Oligoethylene Glycol Side‐Chain Engineering of Y6‐Derived Nonfullerene Acceptors for Thermally Induced Spontaneous Pseudo‐Planar Heterojunction Organic Photodetectors

open access: yesAdvanced Functional Materials, EarlyView.
OEG‐functionalized Y6‐derived acceptors induce thermally driven vertical phase separation, enabling pseudo‐planar heterojunction organic photodetectors. The resulting PM6:YTEG‐4F and PM6:YTEG‐4Cl organic photodetectors suppress dark current density by approximately 260‐fold and 210‐fold, respectively, while maintaining efficient photoresponse ...

Forward‐Biased Perovskite Photodiodes for In‐Sensor Optical Change Sensing

open access: yesAdvanced Functional Materials, EarlyView.
A forward‐biased perovskite photodiode is introduced as an in‐sensor analog preprocessing unit that uses current balancing between photocurrent and injection current to generate optical changes relative to programmable optical reference levels. The device directly converts reference‐relative optical changes into bipolar current signals, enabling sensor‐
