Study of the Effect of an External Magnetic Field on the Photoelectric Properties of a Copper Phthalocyanine Film

In the article the results of n study of the influence of a magnetic field on the change in current-voltage characteristics and charge carrier mobility in a solid film of copper phthalocyanine (CuPc) are presented. A solid CuPc film on a substrata with a conductive ITO surface (Indium Tin Oxide) was obtained by thermal evapo-ration in a vacuum. The absorption spectrum of CuPc was measured: as a result. copper phthalocyanine mol-ecules on the substrate surface were found to be in the metastable a phase. Measurements of current-voltage characteristics (IVC) were carried out using a potentiostatgalvanostat P2OX in the linear sweep mode. To study the effect of a magnetic field on the photoelectric characteristics. a sample was placed between the poles of an electromagnet. A xenon lamp with radiation intensity of 50 mW/cma was used as a simulator of sunlight. As a result of experiments, it was found that the external magnetic field affects the value of the short-circuit current, at the same time, the charge carrier mobility in a magnetic field does not change. The studied effect of a change in the current-voltage characteristics in a solid Cure film upon application of an external magnetic field can he used as a high-speed magnetic field sensor.
