This research line aims at developing organic photodetectors based on multilayer small molecules which deliver a linear change in hotocurrent depending on the position of the impinging light on the pixel. The idea to produce spatial tuning of photocurrent in one single pixel exploits optical interference in multilayer structures as well as antibatic photocurrent response . We have recently developed devices able to monitor lateral displacements with a spatial sensitivity close to 500 mm .
