    Nanostructured Thermoelectric Thin Films Obtained by Wet Chemical Synthesis
    (Sumy State University, 2017) Klochko, N. P.; Kopach, V. R.; Khrypunov, G. S.; Korsun, V. E.; Lyubov, V. M.; Otchenashko, О. N.; Zhadan, D. O.; Kirichenko, M. V.; Nikitin, V. О.; Maslak, M. O.; Khrypunova, A. L.
    Nanostructured pristine lead sulfide and copper iodide semiconductor films as well as copper doped lead sulfide and iodine-enriched copper iodide layers were obtained on solid and flexible substrates via Chemical Bath Deposition (CBD) and Successive Ionic Layer Adsorption and Reaction (SILAR) methods. Crystal structures, optical, electric and thermoelectric properties of the layers have been studied. It was shown that the obtained films deposited on glass and mica substrates are smooth and continuous, have polycrystalline structures of the corresponding bulk semiconductors with grain sizes of several tens of nanometers. Investigations of the optical properties revealed, that their band gaps are characteristic for the corresponding bulk materials. All obtained semiconductor layers are p-type of conductivity. The resistivity of the lead sulphide films were reduced noticeably by means of their doping with copper. Iodination of the copper iodide films convert them into degenerate semiconductors. Investigations of the temperature dependent resistivity, the Seebeck coefficients and power factors confirmed that the obtained materials are promising for their use in thin-film solar thermoelectric generators with the aim of solar heat transforming into electricity.

    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.
