In this study, Cu doped ZnO nanopowders were deposited by hydrothermal method. To investigate the crystalline structure and the orientation of the Cu:ZnO films, XRD patterns were used. The structural, optical and morphological properties of ZnO nanopowders and films were investigated. The effect of Cu dopant concentrations on the morphology of ZnO and the performance of DSSCs were systematically investigated. According to kubelka munk theory, the band gap values of the films were found and the band gap values decreased with increasing Cu concentration. Then, Cu:ZnO-DSSC was fabricated. The current–voltage characterization of fabricated DSSCs was performed by AM 1.5 simulated sunlight at different light intensity. The cell parameters (the short circuit current, the open circuit voltage, the conversion efficiency and the fill factor) of Cu:ZnO-DSSCs were determined.
