Marco Ernst studied in Braunschweig and Hannover, Germany and received the Physics Diplom degree from the Leibniz Universität Hannover, Germany, in 2008. In 2009, he joined the Si thin-film technology group at the Institute for Solar Energy Research Hamelin (ISFH), Germany as a PhD researcher and received a PhD (Dr. rer. nat.) for his research on kerf-free macroporous silicon solar cells from the Leibniz Universität Hannover, Germany, in 2013. In 2014, he joined the Australian National University, Australia, to research laser processes for high-efficiency silicon solar cells.
