ZnO nanometric layers used in photovoltaic cells. In: IFMBE Proceedings. Ediția a 4-a, 18-21 septembrie 2019, Chişinău. Switzerland: Springer Nature Switzerland AG, 2020, pp. 53-56. ISBN 978-303031865-9.978-303031865-9https://msuir.usm.md/handle/123456789/5604https://doi.org/10.1007/978-3-030-31866-6_11The ZnO thin layers were grown on glass, InP and pInP-nCdS substrates from zinc acetate dissolved in water-acetic acid-methanol solution having a molarity of 0.2 M by using the spray method in the argon flow in the temperature range of (250–450) °C. The dependence of optical properties of ZnO layers on growth temperature have been investigated. The optical transmittance has values of 80–85% in the wavelength range of (200–1000) nm. The using of ZnO of the thickness of (60–80) nm as antireflective layers in nCdS-pInP structures allowed to increase the photovoltaic cell efficiency by 3%. The photosensitivity of the fabricated nZnO-pInP structures covers the wavelength region from 450 nm up to 1100 nm and allows the more efficient utilization of the incident light.enzinc oxidenanometric layerssprayingtransmittancephotovoltaic cellsArticle
