The Borchert lab is a group of researchers at the University of Freiburg and Fraunhofer Institute for Solar Energy Systems. Our vision is to develop and understand novel materials for the clean energy solutions of the future. We work on perovskite solar cells with a focus on perovskite-silicon tandem solar cells and perovskite thin-film deposition techniques. At Fraunhofer ISE we form the “Perovskite Materials and Interfaces” group and at the University of Freiburg the “Optoelectronic Thin Film Materials” junior research group. Both groups are interlinked and led by Dr Juliane Borchert.
