PHOTOVOLTAIC PROPERTIES OF POLYMERIC COMPOSITES WITH A TETRANUCLEAR COPPER COMPLEX
Abstract
Photovoltaic and photoconductive properties of styrene-nonylmethacrylate copolymer film composites, poly-n-epoxypropylcarbazole doped with the tetranuclear metal complex Cu4L4(OCH3)4 (L– = N, N'-dibenzyl-N"-trichloroacetyltryes), and sensitizer - an organic compound with intramolecular charge transfer, was investigated. It was found that in the visible spectral range these composites have a hole type photoconductivity, and the internal photoelectric effect is determined by the photogeneration of charge carriers from the metal complex molecules and the sensitizer. The kinetics of formation and relaxation of photogenerated charge carriers was studied by the ESR method. It was concluded that the molecules of the metal complex in the polymer composite increase the efficiency of photogeneration of non-equilibrium charge carriers, and thereby affect the photovoltaic properties of the composites.
