Establishing patterns in the process of forming the response of the electronic subsystem to optical excitation, searching for the relationship between morphology, complex dielectric constant, electrical conductivity and photoelectric conversion efficiency in the latest heterojunctions PEDOT: PSS / Si and PEDOT: PSS / Si-film. Determination of mechanisms for controlling the absorption capacity and ways to increase the lifetime of photoexcited charge carriers and quantum efficiency in solar cells and photodetectors based on them. popup.description2 The project is aimed at finding methods for purposeful formation of the photoelectric response of hybrid metal-semiconductor nanostructured films containing nanosized particles of Ge, SiGe, GeSn, (In,Ga)As, Au, Ag, Cu and organic-inorganic heterostructures InGaAs/GaAs, SiGe/Si/ GeSn/Ge/Si, PEDOT:PSS/Si with quantum dots and 2D materials and establishing fundamental principles for controlling their optical properties. The subject of the research is the processes of photogeneration, recombination, charge and energy transfer during photoexcitation of organic-inorganic heterostructures InGaAs/GaAs, SiGe/Si/ GeSn/Ge/Si, PEDOT:PSS/Si and PEDOT:PSS/NC-film/Si with nanoclusters and 2D materials, physical principles for controlling the efficiency of photoelectric conversion and the effective dielectric constant of solar cells and photodetectors based on them. The object of research is the interaction of electromagnetic (EM) radiation of the optical range with thin-film materials of optoelectronics based on organic-inorganic heterostructures with nanoclusters and 2D materials; photovoltaic converters with nanocrystalline (NC) films, in particular based on heterojunctions InGaAs/GaAs, SiGe/Si/ GeSn/Ge/Si, PEDOT:PSS/Si and PEDOT:PSS/NC-film/Si. Research objective: development of basic scientific principles and principles of controlling the optical and photoelectric properties of organic-inorganic heterostructures with nanocrystalline films with quantum dots and 2D materials.  Product Description popup.authors Isaieva Oksana F.
