- The transition to smart wearable and flexible optoelectronic devices communicating with each other and performing neuromorphic computing at the edge is a big goal in next-generation optoelectronics. These devices should perform their regular tasks supported by energy-efficient in-memory calculations. Here, we study the response of the CsPbBr$_3$ halide-perovskite single crystal fabricated on the flexible polymer substrate and integrated with the single-walled carbon nanotube thin film electrodes in a lateral geometry. We show both photodetection functions combined with the synaptic functionality in our device under the application of hybrid optoelectrical stimuli. Furthermore, we demonstrate that our device exhibits frequency-dependent bidirectional modification of synaptic weight with a sliding threshold similar to biologically plausible Bienenstock-Cooper-Munro learning. The demonstrated optoelectronic synaptic behavior in halide-perovskite single-crystals opens the opportunity for the development of hybrid organic-inorganic artificial visual systems.
