Документ Cadmium sulfide thin films for flexible solar cell received by magnetron dispersion method(Національний технічний університет "Харківський політехнічний інститут", 2018) Zaitsev, Roman Valentinovich; Kirichenko, Michailo Valerievich; Khrypunov, Gennadiy SemenovichFor the purpose of creation of the economic, suitable for large-scale application technology of formation of a layer of wide-scale "window", for thin-film photo-electric converters on the basis of sulfide and telluride of cadmium the pilot studies of temperature effect of a deposition of the films of sulfide of cadmium received by method of magnetron dispersion on a direct current on their optical properties and crystalline structure were conducted. By method of a two-channel optical spectroscopy it is established that a deposition of films of sulfide of cadmium at a temperature of 160 °C allows to form layers with a width of forbidden region of 1,41 eV that approaches value, characteristic of monocrystals, a nd the density of the photon flux passing through a cadmium sulfide layer in a spectral interval of a photosensitivity of telluride of cadmium at the level of 37,0 W·nm·cm2. Body height of precipitation temperature to 160 °C leads to decrease in optical losses in cadmium sulfide films, as a result of increase in the sizes of areas of a coherent scattering and decrease of level of macrodeformations. At further increase of precipitation temperature up to 230 °C the defining factor leading to growth of optical losses in cadmium sulfide films becomes their imp overishment by an easily volatile component – sulfur.Документ Development of electronic load for solar cell testing based on field-effect transistor(2022) Zaitseva, L.

I.; Khrypunov, Gennadiy Semenovich; Harchenko, M. M.In order to create thin-film solar cells based on cadmium sulfide and telluride experimental studies of the process of cadmium telluride magnetron sputtering with direct current, and the impact of a magnetron sputtering mode on CdTe films crystalline structure were carried out. CdTe films for the base layers of thin film solar cells was obtained on flexible polyimide substrates by magnetron sputtering with direct current for the first time. It has found that increasing the magnetron discharge current up to 80 mA leads to increase in coherent scattering regions what is due to an increase in the thickness of the cadmium telluride films of the hexagonal modification having a columnar structure. A further increase in the discharge current leads to a decrease in the size of coherent scattering regions what caused by the thermodynamical output formation of low-angle boundaries. It has shown experimentally that the "chloride" processing of the obtained cadmium telluride layer leads to the transformation of the metastable hexagonal modification cadmium telluride in a stable cubic modification. At the same time, due to the eutectic recrystallization, increase in the sizes of coherent scattering regions by a decade and the microstrain level reduction in 1.5 times are observed.Документ The use of an electomagnetic pulse generator for the study of fast switching processes in cadmium telluride layers(Національний технічний університет "Харківський політехнічний інститут", 2022) Shkoda, D.
