Summary
A theory is proposed for the photoconductivity in CdSe. The material is supposed to be electrically homogeneous in case the photocurrent is much larger than the dark current. In order to compute the concentration of electrons in the conduction band we assumed a band model with two impurity levels. To explain the temperature- and illumination dependence of the photocurrent it proved to be necessary to assume the recombination of electrons in the conduction band and empty states of the lowest impurity level to be of negligible order.
