| Abstract [eng] |
The present study employed the spin-coating method for the preparation of nanostructured crystalline zinc oxide (ZnO) thin films on FTO glass substrates. Subsequently, cadmium selenide (CdSe) layers were deposited on the surfaces using two distinct chemical methods: successive ionic layer adsorption and reaction (SILAR) and chemical bath deposition (CBD). The obtained films were then characterized by a variety of analytical methods, including XRD, SEM, AFM, EDX spectroscopy, UV–vis spectrophotometry, and linear sweep voltammetry. The XRD and SEM studies demonstrated that all of the films exhibited a polycrystalline nature, with the crystallinity of the cadmium selenide thin films prepared using the SILAR method exceeding that obtained by the CBD method. The SEM and AFM images revealed the uniformity of the cadmium selenide films on the FTO substrates, with no visible cracks or pores. The EDX spectra confirmed the presence of the expected elements in the thin films. The optical band gaps (Eg) for CdSe prepared with the SILAR or CBD method were determined to be 1.85 and 1.97 eV, respectively. |
