Abstract

304,132. JotfÚ, A. Jan. 14, 1928, [Convention date]. Drawings to Specification. Light-sensitive cells are formed of a translucent dielectric enclosed between two electrodes which are charged to such a potential that a rapid increase of ionization-current is produced by a change in the strength of the illumination incident on the dielectric. The latter may be formed of interleaved layers of two substances of different composition, such as (1) linseed oil varnish and its oxidation product, or (2) mica and glass or porcelain, or (3) metallic or other conducting or semi-conducting, material interleaved with insulating material. It is found that there is a critical potential-difference for the electrodes, above which the current increases very rapidly with potential-difference. The e.m.f. of the battery is arranged to have about onethird of this value in order to secure maximum light-sensitivity.
