Hummelen, Prof. Kees
Kees Hummelen is professor of Chemistry of Molecular Organic and Bio-organic Materials at the University of Groningen. Together with his staff he is involved in the creation of plastic solar panels. Plastic is significantly cheaper than the resources that are normally used for the production of solar cells. However, the returns are not yet high enough for plastic to be able to compete. The reducing agent Hummelen is using is a special type of polymer, a so-called conjugated polymer, which is coloured and can therefore absorb more light and conduct better. Polymers are long molecules with complex structures. The other substance used, the electron acceptor, is a buckyball, a molecule shaped like a football which consists of sixty carbon atoms.
