Professor Stuart Irvine and Dr Andrew Clayton attended the  2015 E-MRS Fall Meeting and Exhibit held in Warsaw University of Technology.  Stuart gave a very well received invited talk entitled  “Ultra-thin glass: the ideal superstrate for thin film PV”. The main theme of Stuart’s talk was that reducing cost of PV can be achieved through: improved module efficiency, manufacturing volume, yield and materials reduction.  This is an area that the team at CSER are busy researching.
