Dye-sensitized solar cell (DSSC) technology is an interesting and promising inexpensive alternative to the proven solid-state photovoltaic cells. Dye-derivatized mesoporous titania film is one of the key components in such cells.

2,2':6',2"-terpyridine-4,4',4"-tricarboxylic acid CAS: 216018-58-5 was found as the most effective dye component of N749 black dye, which used in DSSC showing an overall conversion efficiency of 10.4%. It is the highest conversion efficiency at that time, which encouraged many scientists have been paid more attention to this area and forwarded the progress a lot.

TiO2 electrodes covered with the complex Ru(L)(NCS)3(L=

2,2':6',2"-terpyridine-4,4',4"-tricarboxylic acid) displayed very efficient panchromatic sensitization covering the whole visible spectrum and extending the spectral response at the near IR region up to 920nm.
