Abstract Among many green energies, research on dye-sensitized solar cells (DSSCs) using solar energy attracts attention. Recent researches have been engaged in the ligand design aiming to improve the photocurrent with a red-shift of the metal-to-ligand charge transfer (MLCT). To increase the absorption in the more red-shifted region, heteroleptic ruthenium(II) complexes were developed with various ancillary ligands in our group. As continuous study based on this idea, we designed new heteroleptic ruthenium(II) complexes by extending the π-conjugation of the anchoring ligand expecting better light harvesting ability. Consequently, we have synthesized new heteroleptic ruthenium(II) complexes with ancillary ligand (4,4`-bis(2-[1,1`-biphenyl]-4-yletheny])-2,2`-bipyridine) and anchoring ligands (different ɑ-diimine ligands). Dye-sensitized solar cells based on some of new ruthenium(II) complexes show noble power conversion efficiencies, which are comparable with that of the standard cell based on N719
