Paper Details

Cuprous oxide (Cu2O) thin films were prepared on to FTO glass substrate by electrodepositionmethod atoptimized bath temperature 60°C and then annealed at varying temperatures of 200°C and 300°C for 1hr each. Thestructural, morphological,optical and vibrational properties of Cu2O thin films were studied using X-ray diffraction(XRD), Scanning electron microscopy (SEM),UV-Visible and Micro Raman spectrometry.X-ray diffraction patternsrevealed that the deposited films were cubic structure with predominant orientation of (111) crystallographical latticeplane and the crystallinityof the film has improved at an annealed temperature 300°C. Since that, the crystallite size (D),dislocation density (δ) and stacking fault probability (α) for preferential orientations are calculated and discussed indetail.SEM micrographs revealed high densed nanoparticle facets of truncated cubes which are more essential forfabricating thin film solar cells.Optical properties of Cu2O films were analyzed by transmittance spectra using UV-Vis-NIRwavelength region. Raman spectra showed that the vibrational peak centered at 637cm-1attributes the formation of Cu2Oin as-prepared and annealed thin films.
