George Koutsourakis’ work focuses on metrology for photovoltaics and semiconductors. He is active in the development of standards for photovoltaics, mainly focusing on new technologies and applications. He is an active member of IEC TC82 “Solar photovoltaic energy systems” and its mirror UK committee GEL/82 - Photovoltaic Energy Systems. George also has significant contributions in the development of standards for photovoltaic devices for indoor light harvesting. He has led and contributed to dozens of R&D and collaborative research and industrial projects at NPL, at a national and international level.
George has photovoltaics technology expertise from PV devices up to PV systems. He has developed several novel characterisation techniques for semiconductors and photovoltaics, including novel methods for luminescence imaging and current mapping. George has established expertise in performance measurement and testing of emerging PV devices, such as perovskite PV devices, organic PV or other emerging PV technologies. He also has experience in performance metrics and monitoring for solar PV systems. He is an optical radiation safety advisor for NPL, mainly focusing on lamp and LED radiation safety.
George Koutsourakis obtained his MEng degree in Applied Physics from the National Technical University of Athens (Greece), followed by an MSc in Energy and Environment at the Physics department of University of Patras (Greece). He acquired his PhD (Electronic and Electrical Engineering) in the area of photovoltaic device characterisation and metrology at Loughborough University, through an iCase award project with NPL.
