ICFO and ICREA
Provided are image sensors with non-local readout circuits that include a substrate and a plurality of pixels and operatively connected to a control unit, wherein the control unit has first and second biasing circuits for providing, respectively, substantially symmetrical first and second biasing voltages and including, respectively, first and second selection means to selectively bias the pixels; and a readout circuit for reading out the pixels; and in that each pixel includes a photo-active element that has a photosensitizing layer associated to a transport layer; a non-photo-active reference element; first and second contacts circuitally connected, respectively, to the first and second biasing circuits; and an output contact circuitally connected to the readout circuit; wherein the photo-active element is circuitally connected between the first and output contacts, and the reference element is circuitally connected between the output and second contacts. Also provided are optoelectronic systems that include the image sensor.
