Abstract
A photoconductive structure comprises an electrically insulating substrate bearing an evaporated metal electrode pattern, and a 60 to 150 nm thick polyimide film disposed between a sintered cadmium selenide layer and the substrate with the superposed electrode pattern. In the absence of the polyimide film, there had been unacceptable attack of the electrode structure and of silica substrates by the cadmium selenide.
