Dye-sensitized solar cells are attracted much interest in the fields of clean energy. In this work, a novel ruthenium terpyridine dimeric complex (N749 dimer) was designed and synthesized through the coordination of 4,4',4"-tricarboxy-2,2':6',2"-terpyridine with ruthenium trichloride, bridging with 4,4'-bipyridine and basic hydrolysis. The calculated and experimental UV-vis absorption spectrums for N749 dimer were compared to those of the commercial black dye N749. The results showed that N749 dimer exhibits wider spectrum absorption range and higher molar extinction coefficient. Dye sensitized solar cells were fabricated based on the N749 dimer. The cell efficiency could reach 2.9% battery efficiency under simulated sunlight irradiation of 100 mW/cm2 power AM1.5G ruthenium. The results provide a new direction for designing the ruthenium dyes.
