Zusammenfassung: 
Calculation of conductivity, and study of photoconductivity and light induced absorption in a iron doped BaTiO3 and KNbO3 are performed at many light intensities. The results are interpreted with the help of two impurity levels bands model. This model allows as to calculate a dark conductivity, to explain behaviour of the photoconductivity with a regard to the light intensities, and to study the light induced absorption coefficient by using impurities concentrations.
