2/14/2023 0 Comments Al xps peak al-chGreater than 85% transparency in the films was obtained in visible and near IR regime as examined by UV–Vis spectroscopy. The formation of wurtzite structure was confirmed, and the crystallite size of the films was estimated by X-ray diffraction (XRD) pattern analysis. In this work, Al-doped ZnO films were deposited on glass substrates by sol–gel spin coating route. To achieve electrical conductivity and transparency via solution processing route, greater insight into the effect of processing and microstructure/defects on the electrical and optical properties is needed. Generally, solution-based processing routes result in lower transparency and greater resistivity. A cheaper, non-vacuum-based routes are required for the large-scale implementation of TCOs in solar cells and LEDs.
