The thin films were immersed in the Eosin Y dye for 24 and 48�h to be fabricated as a dye-sensitized solar cell. ZnO hexagonal wurtzite structures were analyzed by X-ray diffraction analysis. Field effect scanning electron microscope showed the images of ZnO nanoparticles and nanobranches. The atomic force microscopy analysis estimated the average roughness of ZnO�rGO films doped with 0.01, 0.05 and 0.1�wt% which varied from 178 to 267�nm. The electrical or photovoltaic performance of ZnO�rGO were measured and compared accordingly by considering their power conversion efficiency, ?, photocurrent density, Jsc, open-circuit voltage, Voc and fill factor, FF. The cell�s efficiency of ZnO with 0.01�wt% rGO, 0.05�wt% rGO and 0.1�wt% rGO reached ?�=�2.36, 0.78 and 0.38�%, respectively. EIS analysis estimated the effective electron lifetime, ?eff, effective electron chemical diffusion coefficient, Deff, effective electron diffusion length of the photoanode, Ln, charge transport resistance, Rct and transport resistance, Rt. � 2015, Springer Science+Business Media New York.
