I.; Khrypunov, G. S.; Kharchenko, M. M.It has been carried out the 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. In order to create thin-film solar cells based on cadmium sulfide and telluride 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.Документ Attestation of solar cells by back EMF method(Institute for Radiophysics and Electronics of the National academy of sciences of Ukraine, 2014) Lobatenko, D.

R.; Kirichenko, M. V.; Shramko, S. V.; Zaitsev, R. V.It has been shown that to increase the efficiency and manufacturability of single-crystal silicon photovoltaic solar energy converters (Si-PVC) with 180-200 μm thick base crystals having a polished photoreceiving surface and double-layer back surface reflector (BSR) consisting of a transparent oxide and aluminum layers, a conductive transparent indium-tin oxide (ITO) layer of 0.25 μm interference thickness is to be used as the nonmetallic BSR layer. It provides the ITO/Al BSR reflection coefficient in the range of 85 < R < 96 % for solar radiation photoactive component incident the Si-PVC back surface at substantially zero contribution of ITO layer resistance to the device series resistance. In the case of Si-PVC with inverted pyramid type texture of crystal photoreceiving surface at which the specificity of light distribution in the crystal causes total reflection of radiation from Si/ITO interface, the ITO layer thickness should be experimentally optimized in the 1-2 μm range independently of base crystal thickness to minimize the photoactive radiation losses and ITO layer resistance.Документ Effect of extraterrestrial solar UV radiation on structure and properties of ZnO films obtained by wet chemical methods(Vasyl Stefanyk Precarpatian National University, 2019) Klochko, N.

The plasma treatments and antireflection coating deposition on the working surfaces of both single- and multijunction cells were made using the special holders. It was shown that additional treatment of solar cells in argon plasma prior to hydrogen plasma treatment and deposition of diamond-like carbon antireflection films led to the improvement of the cell efficiency by up to 60%. Radio frequency waves support plasma generation and improve photoelectric conversionmainly due to reduction of internal stresses at the interfaces. Application of reactive ion etching technique removes the broken layer, reduces elastic strain in the wafer, decreases recombination of charge carriers in the bulk, and provides cell efficiency increase by up to ten times.Документ Electronic Parameters of a New Thin Film Composition for Kesterite Solar Cell(Прикарпатський національний університет імені Василя Стефаника, 2017) Klochko, N.
