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

ABSTRACT Dark current density ( J D ) fundamentally limits the noise characteristics and detectivity of organic photodetectors (OPDs), arising primarily from reverse‐bias carrier injection and trap‐mediated leakage pathways in donor‐acceptor (D‐A) bulk‐heterojunction (BHJ) active...

Dopant-MediatedStokes Shifting in Perovskite QuantumDots for Enhanced UV-Stable Organic Photodetection

Abstract Ultraviolet (UV) photodetection is critical for applications spanning environmental monitoring to optical communication; however, the high photon energy of UV light introduces inherent trade-offs between sensitivity and operational stability. In particular, organic photo...
