Summary: Titanyl phthalocyanine (TiOPc) thin films were prepared using evaporation and surface polymerization by ion‐assisted deposition (SPIAD) in a vacuum deposition system. These films were characterized by means of ultraviolet and X‐ray photoelectron spectroscopy as well as UV/Vis absorption spectroscopy. Valence band and elemental content indicated that phthalocyanine electronic and chemical structures were largely preserved during SPIAD. Further, bilayer thin films of titania (TiO 2 ) and SPIAD TiOPc were prepared. TiO 2 film was deposited by reactive magnetron sputtering of TiO 2 target. Study of the structured samples was focused on the optical and electrical properties of the composite films. The films were characterized by non‐contact photovoltage measurements and UV‐Vis spectroscopy. These results suggest there is a possibility to use these bilayer thin films in photovoltaic solar cells, however further experiments to improve conductivity of the films will be required.
