Photoelectric properties of the photoconducting film composites based on ferrocenyl‐ and carbazolyl‐containing oligomer doped with polymethine dye

Abstract

New photosensitive polymeric film composites based on oligomer containing ferrocenyl and carbazolyl fragments doped with symmetric polymethine dye are synthesized. Their photoelectric properties are investigated. Photovoltaic properties of these composites are detected. The mechanisms and peculiarities of the photovoltaic and photodielectric effects are discussed.Keywords: Polymeric film composites / ferrocenyl-and carbazolyl-containing oligomer / polymethine dyes / photovoltaic / Dember effect / photodielectric effect / capture of charge carriers Schlüsselwörter: Polymer-Verbundfilme / ferrocenyl-und carbazolylhaltiges Oligomer / Polymethinfarbstoff / Fotovoltaik / Dember-Effekt / Fotodielektrikeffekt / Erfassung von Ladungsträgern
