  Photophysical Studies of Ruthenium-Based Complexes and the Performance of Nanostructured TiO₂ Based Dye Sensitized Solar Cells
  Author(s): Meser M Ali, Wasif Pervez, William Ghann and Jamal Uddin*
  
  Dye-sensitized solar cells (DSSCs) have attracted enormous attention in the last couple of decades due to their relatively small size, low cost and minimal environmental impact. DSSCs convert solar energy to electrical energy with the aid of a sensitizing dye. In this work, two ruthenium-based dyes, tris(bipyridine)ruthenium(II) chloride (Rubpy) and ruthenium(II)2,2’-bis(benzimidazol-2-yl)-4,4’-bipyridine (RubbbpyH2), were synthesized, characterized, and investigated for use as dye sensitizers in the fabrication of DSSCs. The photovoltaic performance of the ruthenium-based DSSCs was assessed. The solar-to-electric power efficiency of the RubbbpyH2 DSSC was 0.2% and that of the Rubpy was 0.03%. The RubbbpyH2 was also deprotonated and analyzed to study the effect of deprotonation on the efficiency of the solar cell. The deprotonated species, .. View more»
