Abstract: The green nanotechnology field has received ample attention and emerged as a viable option for producing nanoparticles (NPs) in an eco-friendly, sustainable, and reliable manner.The rosy periwinkle leaf extract to metal oxide NPs is an encouraging alternative to chemical synthesis.In this study, aluminum (Al), copper (Cu), and zinc oxide (ZnO) nanoparticles (NPs) synthesized using a sustainable technique to evaluate their electrical conductivity and characterized by X-ray diffraction (XRD), ultraviolet-visible (UV-vis), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDX) to determine the crystalline structures and optical properties, functional groups, surface morphology, and elemental compositions of NPs.XRD peaks confirmed that the Al, ZnO were structurally crystalline whereas copper peaks were absorbed as amorphous.In UV-visible spectroscopy, the surface plasmon resonance of NPs is observed at peaks of 237nm, 328nm, and 363nm.FTIR spectra of AlNPs, CuNPs, and ZnNPs were analyzed, revealing distinctive peaks for each.AlNPs showed O-H stretching and carbon group vibrations, CuNPs exhibited carbon and halo compound stretching, and ZnNPs displayed isothiocyanate and carbon group stretching along with metal oxide vibrations.An electrical conductivity test showed that NPs were excellent electrical conductors, making them suitable for photovoltaic solar panel coatings.Thus, Al, Cu, and Zn NPs can used for photovoltaic solar panel coating applications to improve electrical conductivity.
