Abstract

541,739. Selenium cells. VESZI, G. A. July 16, 1940, No. 11757. [Class 40 (iii)] In making photo-electric cells of the kind comprising a selenium base coated with a composite metallic layer by successive cathode sputterings, (1) the first layer is very thin, namely of a thickness which if applied under identical conditions to a transparent or white surface would make the layer only just visible ; and (2) the first laver may be gold and the second layer cadmium. Diffusion between the layers is accelerated by increasing the temperature during the sputtering process for example automatically by the gas discharge. A layer of gold may be applied to the cadmium layer for picking-up the current; this gold layer may be applied by cathode sputtering at a low temperature say 20‹ C. to avoid diffusion. The selenium base may be a film applied to a plate of iron and heated to become light sensitive.
