Zusammenfassung: 
Calculation of dark conductivity, and study of photoconductivity and light-induced absorption in BaTiO3:Fe and KNbO3:Fe are performed at many light intensities. The results are interpreted in a two impurity level band model. This model allows to calculate the dark conductivity, to explain the behavior of the photoconductivity with the respect to the light intensities, and to study the light-induced absorption coefficient.
