(Sumy State University, 2020) Klochko, N. P.; Klepikova, K. S.; Zhadan, D. O.; Kopach, V. R.; Khrypunova, I. V.; Petrushenko, S. I.; Dukarov, S. V.; Lyubov, V. M.; Khrypunova, A. L.
In this work, we study a suitability for protection against terrestrial ultraviolet part of the solar spectrum of undoped and doped by indium zinc oxide thin nanostructured films, ZnO and ZnO:In, respectively, and cuprous iodide (CuI) films obtained via Successive Ionic Layer Adsorption and Reaction (SILAR) techniques on the lightweight low cost poly(ethylene terephthalate) (PET) flexible substrates. The film morphology is observed by scanning electron microscopy (SEM). Chemical compositions of the films are investigated by X-ray fluorescence (XRF) microanalysis. To research crystal structure we used X-ray diffraction (XRD) method. The UV-protection ability of the nanostructured thin films, PET tapes and samples consisting of the PET substrates and the films deposited on them by the SILAR method has been evaluated on the base of their optical properties in accordance with an international standard ISO 2443:2012(E) “Determination of sunscreen UVA photoprotection in vitro”. According to the research, nanostructured ZnO, ZnO:In and CuI thin films made by the cheap, affordable, and suitable for mass production SILAR method on thin flexible cheap PET substrates have been proposed as a new material for UV-shielding applications. In accordance with an international standard ISO 2443:2012(E), UV-protection ability of the samples consisting of the PET substrates and the films deposited on them by the SILAR method fits the category “excellent” (50+). The best low cost flexible and lightweight UV shielding material turned out to be that consisted from ZnO:In film and PET substrate, the sun protection factor of which equals 157.
Effect of Glow-discharge Hydrogen Plasma Treatment on Zinc Oxide Layers Prepared through Pulsed Electrochemical Deposition and via SILAR Method
(Sumy State University, 2019) Klochko, N. P.; Klepikova, K. S.; Petrushenko, S. I.; Nikitin, A. V.; Kopach, V. R.; Khrypunova, I. V.; Zhadan, D. O.; Dukarov, S. V.; Lyubov, V. M.; Khrypunova, A. L.
In this work, we investigated the effect of glow-discharge H₂⁺ plasma treatment on ZnO layers deposited on fluorine doped tin oxide (FTO) glass substrates through low temperature aqueous solution growth, namely, via a pulsed electrochemical deposition and by successive ionic layer adsorption and reaction (SILAR) technique. It is shown that the crystal structure, surface morphology, chemical composition and optical properties obtain some destructive changes after plasma processing due to the creation of oxygen vacancies Vo and H-related defects, and additionally, because of the zinc oxide etching by the glow-discharge H₂⁺ plasma through reduction of zinc oxide and evaporation of Zn from the surface. Neverthe-less, our investigations show quite good stability of the ZnO layers to the plasma-induced radiation and chemical impacts under high total H₂⁺ fluence received by every ZnO/FTO sample ~ 8·10¹⁸ cm⁻².

(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.
Influence of UV light of extraterrestrial solar irradiance on structure and properties of ZnO films prepared through pulsed electrochemical deposition and via SILAR method
(Сумський державний університет, 2018) Klochko, N. P.; Klepikova, K. S.; Petrushenko, S. I.; Kopach, V. R.; Khrypunov, G. S.; Zhadan, D. O.; Dukarov, S. V.; Lyubov, V. M.; Kirichenko, M. V.; Surovitskiy, S. V.; Khrypunova, A. L.
The investigations of effect of long-wave (UVA) and short-wave (UVC) ultraviolet light of extraterres-trial solar irradiance on the nanostructured zinc oxide arrays, which were grown by pulsed electrodeposition, as well as on the ZnO and ZnO:In films produced by Successive Ionic Layer Adsorption and Reaction technique (SILAR) confirmed their suitability as UVA-active photosensitive materials. The crystal structure, surface morphology, chemical composition and optical properties found no obvious significant destructive changes after UVC irradiation. However, we detected some irreversible changes in the nature of point defects under the influence of UVC, which affect the ZnO and ZnO:In resistivity, activation energy, photosensitivity and thermoelectrical properties.
Nanostructured ZnO arrays fabricated via pulsed electrodeposition and coated with Ag nanoparticles for ultraviolet photosensors
(Сумський державний університет, 2018) Klochko, N. P.; Klepikova, K. S.; Petrushenko, S. I.; Kopach, V. R.; Khrypunov, G. S.; Korsun, V. E.; Lyubov, V. M.; Kirichenko, M. V.; Dukarov, S. V.; Khrypunova, A. L.
Nanostructured one-dimensional (1-D) ZnO arrays fabricated via pulsed electrodeposition and coated with Ag nanoparticles are researched with the aim of their using in the ultraviolet (UV) photosensors. The results of the crystal structure investigations showed that the pulsed electrodeposited zinc oxide arrays are polycrystalline in nature and matching with hexagonal wurtzite modification of ZnO. To enhance its UV photosensitivity, the silver nanoparticles (AgNPs) with different shape and an average size of 60 nm, as well as 300-500 nm long Ag nanorods with ~30 nm diameter, are precipitated mainly on the (002), (101) and (100) ZnO planes. Study of electrical properties and electronic parameters of the 1-D ZnO and Ag/ZnO nanocomposites using a current-voltage and capacity-voltage characteristics identified the important role of the high double Schottky barriers at the ZnO intergrain boundaries for the creation of great UV photo-sensitivity. It is proved that through monitoring the amount of AgNPs on the ZnO surface the electrical properties and electronic parameters of the Ag/ZnO nanocomposites, and consequently, the output parameters of the UV photosensors can be controlled.
