Investigation of photovoltaic properties of Al₂O₃ supported Ni (II)-Schiff base complex synthesized by wet chemical method

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 (η%) 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.
