Thin film of composites based on N-epoxypropylcarbazole and n-butylglycidyl ether co-oligomer (GCBE) sensitized by various concentrations of cationic polymethine dyes with different polymethine chain length have been prepared. Their photophysical, electrical, and spectral properties have been investigated. All studied composite films have been shown to exhibited photoconductivity effect. In film composites with high concentration of the dye photovoltaic effect have been detected. The diffusion nature of this effect and its features correlation with electronic properties of PCFs components has been established.
