چکیده

Purpose: in this work, nanocomposite with different weight ratios reduce graphene oxide/copper doping-anatase (rgo/cu-tio2) has been successfully prepared using the photolysis method to evaluate the role of rgo/cu in photovoltaic properties performance application as a photoanodes.materials and methods: the x-ray diffraction (xrd), raman spectrum, and x-ray photoelectron (xps) results analysis confirmed successfully incorporating rgo/cu in the tio2 crystal structure. transmission electron microscopy (tem) reveals the formation of spherical agglomeration nanoparticles with a size approximately equal to 18nm.results: the current density–voltage curves (j-v) and intensity-modulated photocurrent spectroscopy (imps) showed that the incorporation of rgo sheets enhances the ability of n3 loading of (rgo/cu-tio2) photoanodes with faster charge transfer.conclusion: our results illustrate that optimal cu and rgo can increase the efficiency of dye-sensitized solar cells (4.56%) by 8.2% higher than tio2 dsscs (3.52%).
