Klaus Lips is a professor for Experimental Physics at the Freie Universität Berlin and researches renewable energies, with a focus on photovoltaics. He heads a department for materials research at the Helmholtz-Zentrum Berlin, using new analytical methods. Recently, he built the EMIL infrastructure at the Berlin-based synchrotron BESSY II, whose highly brilliant radiation allows insights into the thin layer of modern solar cells, which is only a few atoms thin, thus making it possible to observe the cells’ process of generating electricity.
