Some Characteristics of Lead Sulphide, Selenide and Telluride Photoconductive Cells

Abstract

Measurement has been carried out on the linearity for illumination intensity and the spectral sensitivity of the lead sulphide, selenide and telluride photoconductive cells prepared by the author.
The results of measurements show that the ratio of conductivity during illumination to that before illumination is expressed as a function of incident energy and cell temperature. The spectral response of lead selenide photoconductive cell is also modified by a trace of oxygen during preparing process as in lead sulphide photoconductive cell.
