INAC looks at solar cell dyes

KaïronKem, which specializes in custom synthesis, now sells a line of purely organic dyes (orange, red, and purple) developed by INAC. These metal-free dyes are the result of research INAC has been conducting since 2009. The dyes’ conversion yields still top out at 6%, but thanks to their high absorption they can cut the amount of titanium needed in electrodes by a factor of three—a boon in terms of solar cell production costs.
KaïronKem is one of the first companies to sell the new dyes. The company initiated an EU-funded project with INAC and three other organizations in November 2012. The project aims to develop other 100% organic dyes and incorporate them into PV modules.
