Curriculum Vitae

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. Hummelen is also scientific director of Solenne BV in Groningen.

Hummelen is among the top of his field internationally. He was ranked 7th in the Times Higher Education’s 2011 international ranking list of researchers who have published in the field of materials science over the past ten years. In the same year, he received a EUR 5 million FOM grant to further improve the solar cells.

An article by Hummelen and colleagues, which was published in Science in 1995, has now been cited over 5,000 times.
