Abstract
The present invention relates to novel compounds that are useful as ligands in organometallic dyes. More particularly, the invention relates to dyes comprising the compounds, said dyes being sensitizing dyes useful in solar cell technology. According to an embodiment, the present invention discloses new ruthenium dyes and their application in dye-sensitized solar cells (DSC). The referred ruthenium dyes with new structural features can be easily synthesized, show more than 85% light-to-electricity conversion efficiency and a higher than 9% cell efficiency.
