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.

High molecular extinction coefficient metal dyes

The present invention refers to using the principal of a room temperature molten ionic liquid, to an electrolyte, to devices comprising the ionic liquid co-melting, and to the preparation of a room temperature ionic liquid via various physical and chemical methods. The room temperature molten ionic liquid comprises at least two component salts, at least one of which is not molten at room temperature, but, if combined with another salt, is in the molten state at room temperature.

Eutectic melts

The present invention relates to new organic sensitizer compounds and to photoelectric conversion devices, in particular dye-sensitised solar cells comprising the new sensitizers. The present invention also relates to flexible photoelectric conversion devices, which are based on ionic liquid electrolytes or organic charge transporting materials.
