Abstrakt: In this study, thin films of (Co doped ZnO:CdO) were 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 as well as the effect of grafting on the prepared nanofilms. Research was conducted on. The generated films’ crystal structure using the X-ray diffraction (XRD) technique which revealed that the structure is polycrystalline. The results of AFM also showed The average diameter of the laser energies was (800, 900, 1000) mJ (62.53, 21.92, 9.543) 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 ZnO:CdO-doped PSi/n-Co solar films’ current density–voltage (J–V) characterisation demonstrated—supported by structural and optical investigations—that the conversion efficiency is strongly influenced by the laser power. As the laser power increases, the efficiency (η) climbs from 0.77 to 0.95, while the fill factor (FF) increases from 0.43 to 0.47.
