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 TiO 2 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 (η%) 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.
