Klaus Lips

Prof. Klaus Lips is a faculty member at Freie Universität Berlin, Department of Physics (Experimental Physics), and holds a joint appointment at the Helmholtz Centre Berlin for Materials and Energy where he leads the Institute of Nanospectroscopy. He heads the Working Group 'Advanced Analytics' and serves as the leading manager of the Energy Materials In-Situ Laboratory Berlin (EMIL), a cutting-edge facility for solar cell preparation and synchrotron-based characterization.

His research focuses on fundamental loss mechanisms in solar cells, electronic properties of semiconductors and organic materials, and photon upconversion for third-generation photovoltaics. Through the Joint Berlin EPR Laboratory (BeJEL), Lips investigates performance-limiting defects using advanced spectroscopy techniques including continuous-wave/time-domain electron paramagnetic resonance (EPR), electrically/optically detected magnetic resonance (EDMR/ODMR), photoluminescence, Hall effect measurements, and synchrotron-based methods.

Lips' recent publications predominantly explore spin-dependent phenomena in semiconductors, thin-film solar cell technologies (particularly silicon-based heterojunctions), and quantum computing applications of fullerenes. His work demonstrates strong emphasis on defect spectroscopy, materials characterization, and novel measurement techniques for photovoltaic optimization.

He maintains active public engagement through science outreach including the 'Long Night of Sciences' events and educational programs for kindergartens and schools.
