    A STUDY ON THE STRUCTURAL, OPTICAL AND PHOTOVOLTAIC PROPERTIES OF Fe(II) SCHIFF BASE COMPLEX WITH 5 AMINO-2,4-DICHLOROPHENOL-3,5-DITERTBUTHYSALISYLALDIMINE LIGAND
    (Inst Materials Physics, 2019) Kilinc, D.; Sahin, O.; Horoz, S.
    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.

    Investigation of photovoltaic properties of Al2O3 supported Ni (II)-Schiff base complex synthesized by wet chemical method
    (S.C. Virtual Company of Phisics S.R.L, 2018) Kilinc, D.; Sahin, O.; Horoz, S.
    In our present study, 5-amino-2, 4-dichlorophenol-3,5-ditertbutylsalisylaldimine ligand, Ni (II)-Schiff Base complex and Al2O3 supported Ni (II)-Schiff Base complex were synthesized by wet chemical method. Current density (J)–voltage (V) measurement was performed to investigate the effect of Al2O3 support material on the photovoltaic properties of Ni (II) Schiff Base complex. The power conversion efficiencies (?%) for Ni (II)-Schiff Base and Al2O3 supported Ni (II)-Schiff Base complexes were calculated as 0,72 and 0.85, respectively. This result suggests that Al2O3 supported Ni (II)-Schiff Base complex with ligand which shows higher solar cell performance than pure Ni (II) Schiff based complex, can be used as a sensitizer in DSSC technology. Moreover, the structural, morphological and optical properties of Al2O3 supported Ni (II)-Schiff Base complex were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), Fourier Transform Infrared Spectroscopy (FT-IR) and optical absorption measurements, respectively. © 2018, S.C.

    Investigation of structural, morphological, electronic and photovoltaic properties of Co(II) complex with ligand
    (Springer, 2018) Kilinc, D.; Sahin, O.; Horoz, S.
    The dye sensitized solar cells (DSSCs) used as an alternative to inorganic semiconductor sensitized solar cells (ISSCs), have favorable ecological and economical properties. In our current study, Co(II) complex with 4,4'-methylene bis (2,6-diethyl) aniline-3,5-di-tert-butylsalicylaldimine ligand was used as a sensitizer in DSSC by growing on TiO2 coated on FTO conductive glass substrate. Current density (J) versus voltage (V) measurement was applied to investigate the photovoltaic properties of the synthesized Co(II) complex with ligand. The calculated power conversion efficiency (eta%) of the complex using the obtained current density (J) versus voltage (V) curve shows that this device can be used as a promising sensitizer in solar cell application. Furthermore, structural, morphological and electronic properties of Co(II) complex with ligand were characterized by x-ray diffraction, Fourier transform-infrared spectroscopy, scanning electron microscopy and electronic absorption measurements, respectively.

    Synthesis, characterization and photovoltaic properties of Ni schiff base complex with the ligand of -4,4?-methylene bis (2,6-diethyl) aniline-3,5-di-tert-butylsalicylaldimine
    (Virtual Institute of Physics of the Foundation Horia Hulubei, 2018) Kilinc, D.; Sahin, O.; Horoz, S.
    In the present study, we have synthesized Ni schiff base complex with the ligand of -4,4?-methylene bis (2,6-diethyl) aniline-3,5-di-tert-butylsalicylaldimine at room temperature in aqeous solution. The structural, morphological and optical properties of complex were investigated by XRD, FTIR, SEM, and UV-Vis spectroscopy,respectively. The obtained results show that the complex can be used as a sensitizer in dye-sensitized solar cells (DSSCs). The photovoltaic properties of Ni schiff base complex used as dye sensitizer was studied for the first time. A DSSC was fabricated using Ni schiff base complex with the ligand as the dye sensitizers on nanoporous TiO2 thin film and the photovoltaic parameters of the cells were determined. Our study suggests that Ni schiff-base complex can be used as a suitable sensitizer in applications of DSSCs. © 2018, Virtual Institute of Physics of the Foundation Horia Hulubei.
