Phillip is Associate Professor, Head of the Laboratory for Energy Materials at the University of Luxembourg and Deputy Head of the Physics and Materials Department. He also leads the new Luxembourg Doctoral Training Unit Photovoltaics: Advanced Concepts for high Efficiency (PACE). He received his Ph.D from the University of Bristol in 2004 in the field of colloidal chemistry. Between 2004 and 2007 he began his interest in solar energy as a post doc at the University of Bath. He was then appointed as the first FNR ATTRACT Fellow in 2008 in Luxembourg. His expertise lies in the synthesis and characterization of thin-film semiconductors for PV devices. He has played a leading role in understanding the properties of the earth-abundant semiconductors such as copper zinc tin sulfide (CZTS). He has published 75 papers and 4 book chapters and has 3 patents. He is an international advisor to the UK’s centre for Doctoral Training in Photovoltaics and is a guest editor for the journal Solar Energy.
