Dr. Pierre-Jean Ribeyron received his PhD in 1998 at the University of Grenoble-Alps (France) on the crystallization of multi crystalline silicon for PV application. In 2000, he joined CEA to build the first R&D platform for silicon solar cell technology. Since 2005 and the creation of INES (French National Solar Institute), he focused his research on high efficiency solar cells, especially silicon heterojunction technology. His research interests include the whole value chain from silicon material to module up to PV systems and Levelized cost of electricity.
