Thallous Sulfide Photo‐Conductive Cells I. Experimental Investigation

An experimental study of thallous sulfide photo‐conductive cells is presented. It includes an investigation of the sensitizing oxidation reaction; cell characteristics as function of voltage, temperature, light intensity, wave‐length, modulating frequency, and composition; measurements of thermoeffect and optical absorption; x‐ray and electron diffraction studies, and an examination of the photo‐response to light flashes of very short duration. A theoretical discussion will be given as Part II in a subsequent paper.
