The effect of steady state illumination on the distribution function of the photo‐excited current carriers is considered. It is shown that the energy of the distribution function may be non‐monotonic. This may essentially determine the spectral characteristics of the photo‐current. The dependence of the photocurrent on the optical frequency near the absorption edge may differ from the corresponding dependence of the absorption constant. It is shown that the oscillations of photoconductivity with optical frequency at low temperatures may be due to this dependence of the distribution functions on the nature of the incident light.
