Electric and photoconductivity of the films based on polyvinylbutyral containing nanoparticles of Fe2O3 and CdS and organic compounds with intramolecular charge transfer as sensitizers of the photoconductivity in visible and near IR parts of spectrum are investigated. Within adsorbtion range of the sensitizer, the activation energy of the photocurent slightly exceeds 0.1 eV and it is close to the activa- tion energy of electric conductivity.

Key words: polymeric compositions, nanoparticles, organic compounds with intramolecular charge transfer, electric

conductivity, photoconductivity.
