Prof. dr. Miroslav Zeman received his Ph.D. degree from the Slovak University of Technology in Bratislava, Slovakia in 1989 for research on amorphous silicon materials and devices. In 1990 he joined the Delft University of Technology in The Netherlands where he carried out research on thin-film silicon solar cells. In 2009 he was appointed Full professor at the Delft University of Technology where he led the Photovoltaic Materials and Devices group. Since 2011 he leads the Electrical Sustainable Energy department. Miro Zeman is a leading expert in light management, modelling, and development of novel materials and nanostructures for silicon-based solar cells. Recently his focus has shifted to large-scope applications of PV technology in urban environment. Prof. Zeman published more than 400 articles in scientific journals and conference proceedings and contributed to 6 scientific books. In 2017 the Nankai University in Tianjin, China granted Prof. Zeman the “Guest professorship”.
