Description
Muhammad Ahsan Iqbal and co-authors build an organic detector that sees near-infrared light with striking sensitivity, in a 2024 paper. Organic detectors promise cheap, flexible sensors, but they trail standard ones because the charges born from light stay bound in the film and are lost. Tuning the film to catch infrared light makes the losses worse still.
Their device blends a donor polymer with a strong acceptor so that charge passes wholesale between molecules, forming polarons. Light caught by those polarons frees charges far more easily than plain absorption does, lifting the yield sharply in the infrared band. The detectors sensed light at the femtowatt level at room temperature, with a fast response.
