The rapid advancement of devices that transform light into other energy forms has led to the growth of various solar cell structures established on silicon and other compound semiconductors. Photovoltaic devices that are efficient are required to ensure solar power's competitiveness with traditional energy sources. The most intriguing phase of copper oxides is Cu2O. There have been several findings of Cu2O-based solar cells; nevertheless, their efficiencies are quite minimal due to charge recombination at the crystal boundary and other factors. The goal of the present study is to review the effect of Cu2O thin film thickness prepared by oxidation techniques on efficiency, and then previous related work was systematically studied to investigate their structural and morphological properties. Gravimetric measurements were used to determine the thickness of Cu2O on Cu. The XRD pattern presented shows a single phase of Cu2O with no obvious impurity peaks. The finding shows that when the thickness is 26.30µm, the conversion efficiency is high; image analysis from a different method of deposition demonstrated that the films were compact throughout the entire sample surface, with no observed pinholes. The morphology of the stratum was strongly dependent on the deposition techniques.

“…It means CuO is not advisable to use as photocatalyst to the degradation of dye unless the experimental conditions are changed or surface of the oxide is modified. Tajmeri S. A. Islam et al 22 has investigated that the composite of CuO and Cu 2 O is an efficient photocatalyst for Methylene blue. 95.5% of Methylene blue has been found to be degraded in presence of visible light during three hours irradiation.…”

An environmental benign synthetic route was used for preparation of copper(II) oxide nanoparticles from copper(II) sulphate precursor. Precipitates of copper(II) hydroxide were prepared from CuSO4.5H2O and NaOH. The product was then calcined at 350˚C to get the expected copper(II) oxide nanoparticles. Characterization of prepared sample was carried out by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), FTIR spectroscopy, X-ray powder diffractometry and reflectance measurement. SEM images show that the particle size was less than 100 nm. It is evident from the EDS analysis that the prepared sample was pure and contains only the atoms of Cu and O. XRD pattern confirmed the presence of only CuO in the sample. This result was supported by FTIR spectrum. The prepared CuO was used to study the adsorption and photodegradation of brilliant red (BR) in aqueous medium. The catalytic activity of CuO was investigated and compared with that of commercial CuO. Dhaka Univ. J. Sci. 66(1): 9-13, 2018 (January)
