Professor Stuart Irvine, CSER has edited a new book, “Materials Challenges: Inorganic Photovoltaic Solar Energy” published by the Royal Society of Chemistry. The idea for the book came from the Photovoltaic (PV) SUPERGEN project which was a collaboration of UK Universities to carry out ground breaking research in thin films for PV solar energy. PV SUPERGEN was a £10m funded project which was led by Professor Irvine from 2004 to 2012. It was felt that a book would provide a legacy to capture some of the exciting research and new developments, providing a stimulus for future research. Many of the chapters have been authored by members of the PV SUPERGEN team and also contributors from CSER, Dr Vincent Barrioz and Dr Andrew Clayton. International contributions came from the world leading National Renewable Energy Laboratory in the USA and from Universidad Politecnica de Valencia in Spain. “This has been a rewarding experience and provides an authoritative work on the many research challenges in thin film PV that is very much at the core of research in CSER at Glyndwr University” said Professor Irvine.
