Özet
ZnO photoanodes consisting of nanoflowers were successfully synthesized on FTO substrates in two steps using the seed layer-hydrothermal method. To control the morphological and photovoltaic properties of ZnO thin films, three types of photoanodes were fabricated in the presence of NH3 (C1), NH3-PEG (C2) and NH3-PVA (C3). The morphological and structural properties of the produced photoanodes were investigated by scanning electron microscope (SEM) and X-ray diffraction (XRD). Using these photoanodes, six different types of dye sensitized solar cell (DSSC) were obtained with Ruthenium Dye (Z907) and two different electrolytes. Photovoltaic (PV) and electrochemical impedance spectroscopy (EIS) characterization of DSSCs were performed. The maximum energy conversion efficiencies of these photoanodes in the presence of NH3, NH3-PEG and NH3-PVA were obtained as 1.57, 0.70 and 1.61, respectively, for the same type of electrolyte (AN50) under 100 mW/cm2 illumination.
