Study of the structural and optical properties of copper oxide nanoparticles prepared by plasma jet and their application as solar cells

In this paper, we synthesized copper nanoparticles under atmospheric conditions Using jet plasma in the electrolysis system at different flow rates (0.25 ,0.75,1.75,2.25) and with a constant time and voltage of 6 min, 16 kV, respectively. The cathode was constructed using atmospheric pressure plasma, while the anode consisted of copper tape. Structural and optical properties of CuO nanoparticles were assessed through X-ray diffraction (XRD), with UV-vis spectroscopy employed to validate the characterization of the core CuO nanoparticles. XRD analysis confirmed that there are other peaks associated with secondary CuO phases, and this may be due to the increased flux and the effect of high voltage (16 kV). The copper oxide nanoparticles detected by this method in electrolysis media and preparation time increase in appearance with increasing flow Gradually, indicating an increase in the concentration of the solution. These results support the preparation of these nanostructures for use in gas sensing applications.
