Two ruthenium(II) dye sensitizers of general formulae [Ru(bpy)2(bqdi)](PF6)2 Ru-D1 and [Ru(bpy)2(dmbqdi)] (PF6)2 Ru-D2 (bqdi, benzoquinonedimine, dmbqdi, 4,5-dimethylbenzoquinonedimine and bpy is 2,2'- bipyridine) have been prepared and their structures were elucidated by elemental analysis, mass spectroscopy, magnetic, molar conductance, electrochemical, and spectroscopic (FT-IR and UV-Vis, and 1H NMR) and XRD techniques. The complexes are diamagnetic with octahedral arrangement around Ru(II) ion. Their application as dye-sensitized solar cell (DSC) was investigated.

Dr. Abdulraheem Safar Ali Almalki received his master and Ph.D. degrees from the University of Sheffield (October 2011 – September 2015) in the field of polymer sciences more precisely in the field of solar cells. He subsequently returned to university of Taif, Faculty of Science, Department of Chemistry, KSA as an assistance professor. He was responsible for conducting fundamental research into polymeric materials these include conjugated polymers, composites material, nano-scale materials and hybrid polymers for organic electronics and biological applications. A.S.A. Almalki has many publications in peer-reviewed scientific journals. He is an expert in the trend of design, synthesis and exploitation of the unique physical properties of organic conjugated polymers for application in bulk-heterojunction (BHJ) solar cells and organic light-emitting diodes.
