Документ Development and new application of single-crystal silicon solar cells(2011) Khrypunov, G. S.; Kopach, V. R.; Kirichenko, M. V.; Zaitsev, R. V.Документ Flexible thermoelectric module based on zinc oxide thin film grown via SILAR(2021) Klochko, N. P.; Klepikova, K. S.; Khrypunova, I. V.; Zhadan, D. O.; Petrushenko, S. I.; Kopach, V. R.; Dukarov, S. V.; Sukhov, V. M.; Kirichenko, M. V.; Khrypunova, A. L.In this work, we used the low temperature solution growth Successive Ionic Layer Adsorption and Reaction (SILAR) for a deposition of the nanostructured undoped and indium doped (ZnO and ZnO:In) thin films on flexible polyimide (PI) substrates for their use as cheap non-toxic thermoelectric materials in the flexible thermoelectric modules of planar type to power up portable and wearable electronics and miniature devices. The use of a zincate solution in the SILAR method allows to obtain ZnO:In film, which after post-growth annealing at 300 ◦C has low resistivity ρ ≈ 0.02 Ω m, and high Seebeck coefficient 147 μV/K and thermoelectric power factor at near-room temperatures. As evidence of the operability of the manufactured films as the basis of the TE device, we have designed and tested experimental lightweight thin-film thermoelectric module. This TE module is able to produce specific output power 0.8 μW/m2 at ΔT = 50 K.Документ Electronic Parameters of a New Thin Film Composition for Kesterite Solar Cell(Прикарпатський національний університет імені Василя Стефаника, 2017) Klochko, N.

R.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 New approach to the efficiency increase problem for multi-junction silicon photovoltaic converters with vertical diode cells(Scientific and Technological Corporation "Institute for Single Crystals", 2008) Kopach, V. R.; Kirichenko, M. V.; Shramko, S. V.; Zaitsev, R. V.; Bondarenko, S. A.It is shown, that for efficiency increase of multi-junction photovoltaic solar energy converters with vertical diode cells (VDC) on the basis of single-crystal silicon the modernization of VDC by the introduction along their vertical Si-boundaries single-layer indiumtin oxide reflectors by thickness more than 1 μm is necessary.Документ Back surface reflector optimization for thin single crystalline silicon solar cells(Scientific and Technological Corporation "Institute for Single Crystals", 2007) Kopach, V. R.; Kirichenko, M. V.; Shramko, S. V.; Zaitsev, R. V.; Tymchuk, I. T.; Antonova, V. A.; Listratenko, A. M.It has been shown that for single crystalline silicon solar cells (Si-SC) with 180-200 μm thick base crystals, the optimum back surface reflector (BSR) is TiO₂/Al with 0.18 μm thick oxide layer. At such BSR, the reflection coefficient for photoelectric active sunlight reaching the back surface of Si-SC at 0.88-1.11 μm wavelengths attains 81 to 92 % against of 71 to 87 % at direct Al contact with back surface of silicon base crystal.
