Organo-metallic complexes for DSSC
The Metal Chemistry of our Solar Energy
First reported in 1991 by Professor Michael Grätzel of EPFL (Ecole Polytechnique Fédérale de Lausanne), the use of Ru complexes in Dye Sensitive Solar Cells (DSSCs) is an excellent way to generate energy from a renewable source. In Grätzel´s solar cells, the Ruthenium dye, adsorbed on a thin layer of nanocrystalline TiO2, is used as photo anode while the counter electrode contains Pt.
Besides a low cost and the possibility to be thin, flexible and transparent, Ru based DSSCs feature good performance in direct and diffuse light, which allows them to broadly be used as integrated building sources, indoors, or in mobile electronic devices.
Umicore has scaled up the 3 most effective dyes developed up to now by Grätzel´s group. They are all 3 available at multi-kg scale in quality standards allowing today's DSSCs´ industrial efficiency levels of 6-8%.
