Michael Graetzel

Michael Graetzel pioneered the use of mesoscopic materials in energy conversion systems, in particular photovoltaic cells, lithium ion batteries and photo-electrochemical devices for the splitting of water into hydrogen and oxygen by sunlight. He discovered a new type of solar cell based on dye sensitized nanocrystalline oxide films; mass production started in October 2009. Author of over 1000 publications, two books and inventor of more than 50 patents, his work has been cited over 148 000 times (h-index 176) making him one of the 10 most highly cited chemists in the world.

He has received prestigious awards, including the Balzan Prize, the Galvani Medal, the Faraday Medal, the Harvey Prize, the Gerischer Award, the Dutch Havinga Award and Medal, the International Prize of the Japanese Society of Coordination Chemistry, the ENI-Italgas Energy-Prize and the year 2000 European Grand Prix of Innovation. His most recent awards include the 2012 Albert Einstein World Award of Science, 2011 Gutenberg Research Award, 2011 Paul Karrer Gold Medal and the 2010 Millenium Technology Grand Prize. He was selected by the Scientific American as one of the 50 top researchers in the world.
