V.; Khrypunov, G. S.; Veselova, N. V.; Kirichenko, M. V.; Kharchenko, M. M.; Zaitseva, L. V.For the purpose of creation of thin-film photoelectric converters on the basis of sulfide and telluride of cadmium the pilot studies of process of magnetron dispersion on a direct current of telluride of cadmium and influence of the modes of magnetron dispersion on crystalline structure of films of CdTe are conducted. CdTe films for basic layers of sheet photoelectric converters on flexible polyimide substrate by the method of magnetron dispersion on a direct current are received for the first time. It is experimentally shown that "chloride" processing of the received layers of telluride of cadmium leads to transformation of metastable hexagonal modification of telluride of cadmium in stable cubic. At the same time at the expense of the eutectic recrystallization body height of the sizes of areas of a coherent dispelling much and decrease by 1,5 times of level of microstrains is observed.Документ Methodological instructions for laboratory works from the course "Fundamentals of computer science and computer engineering"(2022) Riazanova-Khytrovska, N.

V.The current problem is the autonomous supply thermal energy and hot water for civilian and military consumers. The most commonly used for this purpose are installations based on solar thermal collectors, which at the same time require an external power source up to 100 W for electronic control components and a circulating pump, which does not allow them to be fully considered as autonomous. One of the ways to solve this problem is to combine in one installation solar panels and heat collectors. It has been proposed the constructive technological solution of the hybrid photoenergy system with flexible solar cells based on cadmium telluride, which allows getting the total efficiency of such a system up to 73% for the transformation of solar energy into heat and electric energy.Документ Hybrid solar generating module development for high-efficiency solar energy station(Сумський державний університет, 2018) Zaitsev, R. V.; Kirichenko, M. V.; Khrypunov, G. S.; Prokopenko, D. S.; Zaitseva, L. V.Experimentally established, the influence of the working temperature and solar radiation power on the efficiency of industrial production silicon solar cells. Based on the experimental results designed the concept of a hybrid solar generating module equipped with a mirror concentrator of solar radiation and solar cells cooling system for using in high-performance solar energy station. Concentrator of solar radiation provides in 1.5-time increase of electrical power generating by such module, and water-cooling system can reduce the equilibrium temperature of the module up to 10 degrees and twice reduce efficiency losses from solar cells overheating. The proposed concept will reduce the number of modules needed to build solar energy station.Документ Operating temperature effect on the thin film solar cell efficiency(Сумський державний університет, 2019) Zaitsev, R. V.; Kirichenko, M. V.; Khrypunov, G. S.; Radoguz, S. A.; Khrypunov, M. G.; Prokopenko, D. S.; Zaitseva, L. V.The made research results of the dependence of the film photovoltaic converter efficiency on their operating temperature and their comparison are considered in the paper. The physical mechanisms of temperature influence analysis on output, diode and electronic parameters of photovoltaic converters were conducted. The output parameters determination of the flexible photovoltaic converters was carried out by measurement of light current-voltage characteristics by using illuminator based on powerful semiconductor LEDs with different colors for simulated radiation which is close to the standard ground and ultraviolet solar spectrum. For ensuring effective non-destructive switching of the test specimens of the flexible PVC based on cadmium telluride to the measurement circle, the special contact device was developed and used. The main feature of contact device is four separate vertically moving metal probes in form of semi spheres with polished surfaces, which makes it impossible to puncture the PVC electrodes. These probes have possibility of individual positioning of each probe that is carried out with the help of a hard rotary console of variable length attached to the body and can be pressed with a given effort without impact on the frontal and any rear electrodes of the PVC experiments. The efficiency temperature coefficients of the photovoltaic converter, which make up for devices with a CdTe of 0.14 %/C, CuInSe2 – 0.36 %/C, amorphous silicon - 0.21 %/C were obtained. The analytical processing and analysis of the light diode characteristic effect on the PVC efficiency based on the CdTe showed that the temperature stability of their efficiency is ensured by the diode current density, the incision of which increases by 50 % from 1.9·10 – 9 A to 2.7·10 – 9 A with the temperature rise from 20 °С to 50 °С. At the same time, it has been established for PVC on the CuInSe and amorphous silicon base that the decrease of short circuit current density, open circuit voltage and fill factor of current-voltage characteristics plays the main role in efficiency reduction with rising temperature.
