ABSTRACT:
This photoelectric detection device comprises a matrix of elementary detectors on an insulating substrate. Each of the elementary detectors has a stack consisting of a lower electrode, a layer of a photosensitive material and a phototransparent upper electrode. The upper electrode is common to all the elementary detectors. Each of the lower electrodes is connected independently of one another to a sense circuit. The lower electrodes are each positioned on an individualized insulating zone, which is raised with respect to the insulating substrate. Furthermore, the upper electrode is not flat and is inserted between two adjacent zones until it reaches a level below that of the lower electrodes.
