Klaus Lips

Prof. Dr. Klaus Lips is a Professor at the Helmholtz-Zentrum Berlin für Materialien und Energie (HZB), leading the Energy Materials In-Situ Laboratory Berlin (EMIL) and the Joint Berlin EPR Laboratory (BeJEL). His research focuses on characterizing fundamental loss mechanisms in solar cells, electronic properties of semiconductors, and photon upconversion for third-generation photovoltaics. He holds a doctorate from Philipps-Universität Marburg (1994) and has held roles such as Deputy Director of the Institute for Silicon Photovoltaics at HZB. His work integrates advanced techniques like EPR, THz-EPR, and synchrotron-based methods.
