Abstract

593,808. Light - sensitive cells.ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Feb. 12, 1945, No. 3429. Convention date, March 4, 1944. [Class 40 (iii)] [Also in Group XXXVI] A method of producing a barrier-layer selenium photo-electric cell includes the step of treating the selenium surface adjacent to the counter electrode with one or more of the metals thorium, hafnium, zirconium, titanium or the rare earth metals or their compounds other than halogen compounds. The metal or metals may be applied to the selenium surface by condensation of the vapour of the desired metal, by cathode sputtering, by spraying in a liquid state an alloy of the metal and the counter-electrode or, by treating with a solvent containing a compound of the desired metal in solution. The compound may consist of a nitrate, nitrite or an organic compound and the solvent may be alcohol or other organic solvent.
