Cis-bis(isothiocyanato)bis(2,2′-bipyridyl-4,4′-dicarboxylato)ruthenium(II), also known as N3 Dye, is one of the earliest benchmarked ruthenium complex dyes developed for high-efficiency dye-sensitized solar cells (DSSC). Since its discovery, it has become the paradigm of heterogeneous charge-transfer sensitizer for mesoporous solar cells.
cis-Bis(isothiocyanato)bis(2,2′-bipyridyl-4,4′-dicarboxylato)ruthenium(II) (N3 dye) is a ruthenium polypyridyl based complex that can be used as a sensitizer. It is a highly stable polymer in which the photocurrent decreases with an increase in the concentration of N3 dye.
