“…In order not to exacerbate the problem, diversification of the energy system is required, where renewable energy sources will play a main role because, according to various estimates, by 2030, the share of such types of energy will be about 30-35% of the world's energy production, and it's realistic, because the exploitation of solar energy is very convenient. For example, with the help of solar panels, solar ovens, and solar collectors, we can get electricity and heat energy; using solar energy, it is possible to produce hydrogen, which is also necessary for decarbonization; from solar ovens for various purposes, it is possible to obtain high temperatures and also using solar air collectors it is possible to develop a conveyor device for drying various types of fruits and cocoons, which are used in the agro-textile industry and using solar radiation in polymeric materials we can determine their resistance, as well as test them for light fastness [1][2][3][4][5][6].…”

This article is about a photovoltaic power plant built at the Korean side's expense, equipped with Korean-made solar panels, and where the author conducted scientific and practical research. The study used a scientific-practical, observational, comparative measuring method. All solar panel trackers were set at 30° degrees and not equipped with a sun tracking system, except for only one solar panel. The tracker of the TOP SUN module has a manual tracking system for the Sun, in which a person has to manually changes position from 15° to 45° degrees depending on the seasons. Thanks to the authors, a solar tracker has been developed to improve the efficiency of solar panels, which has a sun tracking system and low energy consumption, which is a key aspect. During the day, the solar panel parameters with and without a tracking system for the Sun were obtained; also, their power was calculated, and for comparison, a graph of the power difference was plotted. On average, a solar panel with a solar tracking system generates 30 % more energy than a solar panel without a tracking system.

( Z )-6-alkylamino-2-Amino-4-(2-aryl-1-cyanovinyl)pyridine-3,5-dicarbonitriles were obtained by reaction of ( Z )-2-amino-4-(2-aryl-1-cyanovinyl)-6-chloropyridine-3,5-dicarbonitriles with various amines, including biologically active ones. The study of the spectral-luminescent properties showed the solid state fluorescence with a maxima at 472-562 nm and its absence in solutions. An increase in the volume fraction of water in solutions above a certain level caused the appearance of fluorescence due to the formation of aggregates. The enhancement of fluorescence upon addition of the viscous solvent glycerol confirmed the presence of aggregation-induced emission of the synthesized compounds.
