Nanostructured Solar Cells

Sascha Sadewasser is the Group Leader of the Laboratory for Nanostructured Solar Cells. Sascha is interested in developing materials and devices for photovoltaic energy conversion, such as building-integrated photovoltaics, light-weight flexible solar cells, etc. He is an expert in Kelvin probe force microscopy, which he applies to the characterization of semiconductors, thin-film solar cell materials and 2D materials. His group develops advanced concepts for chalcopyrite thin-film solar cells, ranging from passivation layers and micro-concentrator solar cells to quantum dot and nanowire concepts. The group also works on 2D chalcogenide materials for optoelectronic applications.

Sascha Sadewasser holds a Diploma (1995) in Physics from the RWTH Aachen, Germany and a PhD (1999) from the Washington University St. Louis, MO (USA). He did a post-doc (1999-2003) at Hahn-Meitner Institute Berlin (Germany) and was a Ramón y Cajal scientist at the Centro Nacional de Microelectrónica in Barcelona (Spain) from 2003 to 2004. From 2005 until 2011, he was the group leader of the Nanoanalytics and Nanofabrication group at the Helmholtz-Zentrum Berlin (Germany) and the deputy head (2008-2011) of the Department for Heterogeneous Materialsystems. In 2011, he obtained his Habilitation in Experimental Physics from the Free University of Berlin (Germany). Since July 2011, he has been the Principal Investigator of the Laboratory for Nanostructured Solar Cells (LaNaSC) at INL. Additionally, at INL, he took the responsibilities of Coordinator of the Energy Research Area (2015-2016), Head of the Department for Quantum and Energy Materials (2018-2019) and Coordinator of the Clean Energy Cluster (2020 and 2022).
