Abstract

Precise and facile junction engineering of organic photodiodes (OPDs) via chemical doping is demonstrated. This method is different from previous narrowband detection strategies, in that only the depletion region width, not the overall thickness of the active layer, is controlled to realize thin-film narrowband-selective OPDs for noise-tolerant optical sensors.
