| Abstract: | Three new amphiphilic ruthenium complexes (Ru-1, Ru-2 and Ru-3) based on phenanthrenyl derivatives have been synthesized and used as photosensitizers for dye-sensitized solar cells (DSSCs). The ruthenium complex Ru-1 containing a carbazole group showed especially improved photophysical properties (red-shifted metal-to-ligand charge-transfer transition absorptions and enhanced molar extinction coefficients) and interesting electrochemical properties, resulting in its improved open circuit potential and high overall light-to-electric power conversion efficiency of 5.3% (AM1.5, 75 mW/cm2). These facts indicate that the carbazole-based phenanthrenyl ruthenium complex is a promising candidate for improving the conversion efficiency of dye-sensitized solar cells. |
