Description
Yijing Fan and co-authors boost organic light detectors with a molecular interface layer in a 2026 study. A common hole-transport polymer suffers from an insulating phase that gathers at its surface and blocks charge flow. A self-assembled monolayer of a carbazole phosphonic acid was added to tame that interface.
Dark current fell, energy alignment improved, and recombination losses shrank in the double-layer device. Peak response reached strong levels in near-infrared light, with detectivity in the high range for organic devices. Speed, bandwidth, and linear range each improved markedly over the single-layer reference, the first by about fourfold. Sensor engineers gain a cheap interface trick with broad gains. Weak-light cameras, health monitors, and optical links all prize exactly this mix of low noise and fast response.
