The influence of the control voltages on the photoelectrical characteristics of the photocell with three vertically integrated --junctions has been studied. The time diagrams of the control impulses for the - and -regions as well as their spectral characteristics have been presented. The dependences of the surface concentration of the photocarriers, generated in SCR n-and p-regions, on the photo exposure, as well as the dependences of photo currents in the - and -regions of the photosensitive photocell with three vertically integrated --junctions on the illumination of absorbed optical radiation have been obtained.
