Novel Schiff base ligand, N,N’-phenylenebis(salicylimine) (SALPHEN), and its
Co(II), Cu(II) and Fe(III) transition metal complexes were prepared, and
characterized by analytical methods. The results obtained elemental analysis,
Fourier transform infrared; UV– visible, molar conductance, magnetic
susceptibility, thermal analysis and X-ray powder diffraction (XRD): showed that
the synthesized complexes are in octahedral geometry, the metal ion binds with
ligand via two oxygen, two nitrogen atoms, the fifth and sixth position are
occupied by two chlorines atoms . The synthesized complexes were used as
sensitizer to study the efficiency of dye-sensitized solar cell (DSSCs) and were
compared with the standard ruthenium dye. The solar cell was fabricated using
graphite as photo cathode, TiO2 as photo anode and I-/I3- as electrolyte. The
sensitizers (Ruthenium dye, [Co(SALPHEN)Cl2], [Cu(SALPHEN)Cl2] and
[Fe(SALPHEN)Cl2]) were varied and the conversion efficiency of solar cell was
investigated. The [Cu(SALPHEN)Cl2] is expected to show conversion efficiency
nearer to the standard ruthenium dye.
