Abstract
A photoconductive device having a transparent substrate, a transparent conductive film, a photoconductive film and a layer of an insulator provided on at least part of the substrate and of high thermal conductivity, and a method of operating the photoconductive device. Thus, especially, the temperature of a photoconductive film of an imaging device typical of an image pick-up tube or the photoconductive device which may be a one- or a two-dimensional image sensor or a photocell can be controlled precisely and efficiently.
