Abstract
Short‑wave infrared (SWIR, 1.0–2.5 μm) imaging is relevant to autonomous systems, machine vision, and low‑light biomedicine where deeper penetration, material contrast, and eye‑safe illumination are required. Organic photodetectors (OPDs) are promising because they are solution‑processed at low temperature and their bandgap can be tuned molecularly. Recent donor–acceptor designs extend optical response to SWIR region. The main challenge is not reaching SWIR absorption, but converting those photons efficiently: maintaining charge collection at low photon energies while suppressing leakage remains difficult. This poster reviews the current SWIR‑capable OPD landscape and focuses on practical levers—stabilizing closed‑shell ground states, removing unintentional doping, implementing and selective blocking contacts—to activate long‑wavelength absorption into real EQE and to outline a path toward reproducible, scalable SWIR OPDs.
