In this study, we demonstrate the intrinsic benefits of organic MISM photodetectors, namely their effective operation under high steady-state lighting, responding only to changes in light intensity, and their ability to react to several light sources simultaneously. Furthermore, the strong interaction at the S/I interface, specific to this architecture, significantly enhances the device photoresponse, resulting in highly efficient differential photodetection, compared to a composite MSM + C device fabricated from identical elements.}, title = {A differential photodetector: Detecting light modulations using transient photocurrents}, volume = {6}, year = {2016} }
