"Diligent analysis"
Johannes Bernreuter is a higly qualified journalist in the photovoltaic space whose carefully researched and clearly written reports on market, industry and research I have learnt to appreciate since quite some time. Specifically, his diligent analysis of new developments in the area of silicon feedstock material provides well-founded insight for specialists in the PV field as well as non-experts. Eicke Weber

- Eicke Weber
Eicke Weber has been director of the renowned Fraunhofer Institute for Solar Energy Systems (ISE) in Freiburg (Germany) and incumbent of the Chair for Applied Physics, Solar Energy, at the University of Freiburg since July 2006. Previously he taught at the Department of Material Science and Engineering of the University of California in Berkeley for 23 years.
Weber is considered as one of the worldwide leading experts for the characterization of defects in silicon and so-called III-V semiconductors like gallium arsenide and gallium nitride. He has been working on a method of clustering metals contained in silicon by temperature treatment so that less pure and more inexpensive silicon ("dirty silicon") can be used as a feedstock for the production of solar cells.
