Nicolas Wyrsch was born in 1960 and studied physics at the ETH Zurich. After obtaining his diploma in 1984 he joined the group of Prof. Shah at the Institute of Microtechnology (IMT) of in Neuchâtel to contribute to the development of a-Si:H solar cells, focusing on the study electronic properties of the material. After a stay at Princeton University he obtained his Ph.D. from the University of Neuchatel in 1991. Since then he is team leader in the laboratory of photovoltaics (PV-LAB) of the Ecole Polytechnique Fédérale de Lausanne. His interests and main activities are focused on particle sensors and imagers, the integration of photovoltaic systems in the electric grid, including storage and building energy management, and PV module energy efficiency and lifetime.
