In this study, thin films of (Cr doped ZnO: CdO/Si) deposited on glass substrates, and nanofilms were obtained using an Nd-YAG laser with a wavelength of 1064 nm at different laser energies (800, 900, and 1000) mJ. The properties of determination of the thin films using different methods for investigating the impact of laser energy and the effect of grafting on the prepared nanofilms. The research was conducted on. The crystal structure generated by the films was used the X-ray diffraction (XRD) technique revealed that the structure is polycrystalline. The results of AFM also showed that. The average diameter of the laser energies was (800, 900, 1000 ) mJ (39.18, 31.12, 29.62 ) nm, respectively In addition, there is an increase in the roughness of the surface of the nanoparticles. While increasing the energy of the prepared films leads to an increase in the optical energy gap values. Finally, the Cr doped ZnO: CdO/Si solar films’ current density–voltage (J–V) characterisation demonstrated supportedby structural and optical investigations that the laser power strongly influences the conversion efficiency. As the laser power increases, the efficiency (η) climbs from 0.41 to 0.91, while the fill factor (FF) increases from 0.60 to 0.45. |
