TiO₂ nanotube-based dye-sensitized solar cell using new photosensitizer with enhanced open-circuit voltage and fill factor.
We report the synthesis and characterization of a high molar extinction coefficient ruthenium complex sensitizer (Ru (6,6'-(COOEt)(2)-2,2'-bpy)(2)(Cl)(2)). In conjugation with TiO(2) nanotube arrays as a photoactive material and iodine/iodate redox electrolyte, we fabricated efficient dye-sensitized solar cell device showing a conversion efficiency of 3.94% measured under the air mass 1.5 global (AM1.5G) sunlight. The solar cell device showed a reasonably high open circuit voltage (0.74 V) as well as a fill factor of 0.63.
