is made of a truncated shape at an angle of 450, the anomalously strained film is doped with ge, a reflective layer of aluminium al is applied to the inner surface of the substrate, and contacts are simultaneously sprayed onto one of the end sides of the abnormally photo stressed film, all end sides of the photo generator, except truncated, covered with an opaque layer. increased photovoltage, photosensitivity and reliability of the photo generator operation are achieved by the fact that an alloying layer of germanium ge is applied to the film, the reflective layer is made of aluminium al, one end side of the substrate is truncated at an angle of 450, contacts are made on top of one of the end sides of the film, on all end side of the photo generator, in addition to the truncated one, a light-proof layer is applied, and also because one …

ed at an angle of 450 between the direction of the molecular beam and the normal to the substrate. fig. 1. small-sized photo generator devices. the photo generator works as follows. through the end truncated side 6 of the substrate 1, which is a light-transmitting section, the light flux with the illumination of 104 lx enters the light-absorbing afs film 2 of cadmium telluride, on which the dopant layer 5 of ge germanium is located. part of the incident light flux with intensity io, passing through the end truncated side 6, hits the reflective layer 3 of aluminium al and is reflected from it, enters the light-absorbing film 2 of cadmium telluride, as a result, additional absorption of light occurs and the generated photo-voltage increases. when the flow of light enters the light-absorbing film 2 of cadmium telluride, the light flow is converted into an electric voltage in it. the …
