Özet
In our present study, 5 amino-2,4-dichlorophenol-3,5-ditertbuthysalisylaldimine ligand was synthesized and we used this ligand to prepare its-Fe(II) complex with using the wet chemical method. The structural, optical and electronic properties of Fe(II) Schiff base complex with ligand were characterized using the x-ray diffraction (XRD), optical absorption and Fourier transform-infrared (FT-IR) measurements, respectively. The structure of Fe(II) Schiff base complex with ligand was determined as a monoclinic crystal system. Two absorption bands were observed in the UV-visible region. They are assigned to intraligand and charge transfer transitions, respectively. The FT-IR spectra of Fe(II) Schiff base complex with ligand are similar to the ligand spectra. Despite the similarity, a shift toward higher frequencies was observed in the vibration modes of azomethine groups. Furthermore, Fe(II) Schiff base complex was used as a photosensitizer on TiO2 film in a DSSC device. Thus, the effect of Fe(II) Schiff base complex on the efficiency of DSSC device was investigated and photovoltaic parameters such as power conversion efficiency (eta), open circuit voltage (V-OC) and short circuit current density (J(SC)) were determined. The obtained J(SC) and V-OC value for samples is 3.75mA/cm(2) and 600 mV, respectively. The. % value was calculated as 0.80. Our result leads to obtain improved conversion efficiency of Fe(II) Schiff base complex with ligand based DSSC device.
