Structure‐Controlled Cyclopentadithiophene Derived Non‐Fullerene Acceptors for Efficient Near‐Infrared Organic Photodetectors

Small, Volume 22, Issue 43, 3 August 2026.
This work demonstrates high‐performance solution‐processed NIR OPDs using DTP‐ and DTTP‐based NFAs (OC and SC), where donor‐core engineering enables tunable absorption and balanced optoelectronic properties; notably, DTP‐based devices achieve broad NIR response, low dark current, and high detectivity, highlighting their potential for advanced NIR ...

Advancing Retina Implant Concepts: Assessing the Design and Validation of Origami‐Type Epiretinal Implants by Computational Modeling

physica status solidi (a), Volume 223, Issue 14, 22 July 2026.
We utilize a simulation framework including axon map models generated from earlier human trials to predict the neural activation of a novel, origami‐type epiretinal implant. With this, we can assess its expected performance compared to other implants and significantly shorten the development of novel implant concepts in the future.

Nanophotonic Design of Germanium‐Silicon Single‐Photon Detectors for Integrated Quantum Photonic Circuits

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
Nanophotonic Ge/Si single‐photon avalanche detectors (SPADs) employing photonic‐crystal‐enhanced optical confinement and a separate absorption–multiplication (SAM) architecture enable near‐unity internal quantum efficiency, low dark current, sub‐50 ps temporal response, and efficient telecom‐band single‐photon detection.
