Lutsyk P. Electronic processes at the interface of organic semiconductors

The thesis deals with the investigation of interface properties of photosensitive organic semiconductors. The influence of annealing and substrate temperature during thermal deposition on energy structure of excitons, optical and photovoltaic properties of the films of SnCl2 phthalocyanine, methyl substituted perylene pigment and hexathiopentacene was studied. The optimal conditions were determined for preparation of aniso-type heterostructures based on methyl substituted perylene pigment and iso-type heterostructures based on pentacene that are perspective for the development of organic solar cells. It was determined that obtained results for aniso-type heterostructures agree with energy diagram of Anderson approach and for iso-type heterostructures are described using Van Opdorp model.
