It optimizes the geometry and morphology of photovoltaic cells based on heterojunctions PEDOT:PSS/Si and PEDOT:PSS/NC-film/Si to create conditions for the most effective absorption of visible light and correspondingly enhance the efficiency of photoelectric conversion. Optical and electrical properties of semiconductor nanocrystalline films CZTS, PbI2, and AlN:Er have been investigated.It was demonstrated that adding an NC-film to the photovoltaic cells based on heterojunctions PEDOT:PSS/Si increases their efficiency. A technology has been developed to obtain hybrid nanostructured films with a predetermined spectral absorption range and photosensitivity, determined by the morphology of nanostructures. Their primary parameters are comparable to the best global analogs.The practical value of these results lies in their potential utilization for a new type of silicon-based solar elements (photodetectors, solar cells) with improved parameters due to the use of hybrid organic-inorganic nanostructured films with semiconductor nanoclusters and 2D nanostructures. Successful implementation of these research results could lead to the establishment of advanced solar element production based on silicon technology. Further research will facilitate the development of advanced materials for photovoltaics and optoelectronics with predetermined optical and photoelectric properties.The research outcomes of hybrid nanostructured films with quantum dots and 2D materials on the surface of monocrystalline silicon could be used for the development and subsequent patenting of new types of photosensitive optoelectronic devices. These could include highly sensitive dual-purpose IR devices. Product Description popup.authors Isaieva Oksana F. Datsenko Oleksandr I. Dzhahan Volodymyr M. Mykytyuk Anastasiia О.
