Документ Double-layer ITO/Al back surface reflector for single-junction silicon photoconverters(Scientific and Technological Corporation "Institute for Single Crystals", 2008) Kopach, V. 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 Hybrid photoenergy installation development(2018) Zaitsev, R. V.; Kirichenko, M. V.; Krypunov, G. S.; Zaitseva, L. 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 High-voltage DC converter for solar power station(Institute of advanced engineering and science, 2020) Qawaqzeh, M.; Zaitsev, R. V.; Miroshnyk, O.; Kirichenko, M. V.; Danylchenko, D.; Zaitseva, L. V.In the article the circuit design solution of DC-DC regulated resonant converter has been proposed for using with hybrid photovoltaic modules which has cooling equipment and solar concentrators in order to maximize electric power generating by such module. By using computer simulation based on multiple iterations algorithm we significantly increase the accuracy of determining the resonance circuit optimal parameters for build up DC–DC converters to work in a wide range of electric powers. Based on optimal values of the resonance LLC scheme parameters, achived by numerical calculation it can be show high values of electrical energy transformation efficiency for photovoltaic energy station equipped with high efficiency hybrid photovoltaic modules. Implementation of microprocessor-based control into design of DC–DC back-boost converters create a new possibility to build control algorithms for increase reliability and conversion efficiency, rapid and precision stabilization of maximum power point, implementation network monitoring of photovoltaic modules, converters itself and the whole photovoltaic station parameters.
