Abstract
498,503. Photo-electric cells. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. April 3, 1937, No. 9527. Void. Convention date, April 6, 1936. [Class 39 (i)] A photo-electric cell has an electrode which is impervious to active light and comprises an adsorbed layer of photo - electric metal but contains no excess of free metal, and a window through which the light passes, the inside of the window being coated with a coherent metal layer which is not covered with a photo-electric layer, is conductively connected to one of the electrodes, and is thin enough to transmit a substantial proportion of the light. In the form shown, the bulb 1 contains a tungsten filament 6, coated initially with silver, and acting finally as the anode. The filament is heated to evaporate a silver layer 7, 0À01-0À1 mm. in thickness, onto the bulb, screens 8 and 10 preventing deposition on the window 9 and stem 3 respectively. A discharge is passed in argon at 0À1 mm. between the layer 7 and electrode 6, during which a thin layer of silver 11, of 0À005-0À01 micron thickness is sputtered upon the window 9. The silver is then oxidized by a discharge in oxygen at 0À1 mm. and treated with caesium vapour. The layer 11 may be evaporated after the layer 7 has been oxidized, and may comprise platinum, tungsten, or molybdenum, having melting points exceeding 1500‹ C.
