Jig-sensitive optical detectors based on semiconductor films with anomalous photovoltage

The photoelectrical properties of anomalous photovoltaic (APV) CdTe, CdTe:Ag films have been investigated. For the first time it was established that if the back side of the film is put on a silver-plated substrate, the APV effect in such film increases to 30%. On the basis of these films the self-contained optical radiation receivers and photoelectronic transformers for sensitive control of coordinates of moving objects have been developed. In coordinate-sensitive photogenerators on a basis cadmium telluride films it is possible to develop the coordinate-sensitive independent receiver of optical radiation. The entrance signal contains the information on a direction and size of displacement of radiating object. On the basis of such films the coordinate-sensitive independent receiver of optical radiation “КЧП-1M” was made.
