GUEST SPEAKERS

James Durrant is Professor of Photochemistry in the Department of Chemistry at Imperial College London and Sêr Cymru Solar Professor in the College of Engineering at Swansea University. He is also the Director of the Centre for Plastic Electronics (CPE). His research interests are the photochemistry of new materials for solar energy conversion and is currently addressing the development and functional characterization of organic and perovskite PV cell and the photocatalysts for solar driven fuel cells. Professor Durrant is a Fellow of the Royal Society and Fellow of the Learned Society of Wales.

Ingrid Romjin joined ECN Solar Energy in 2004, where she started working as a researcher and later as a project leader (2006) in the crystalline silicon group. The research topics involved (o.a.): research on passivating layers, optimization of SiNx deposition systems and (advanced) solar cell concepts. Since 2012, Ingrid Romijn is program manager for bifacial PV at ECN Solar Energy. From 2014 to present, she also works as team leader and deputy senior manager in the Manufacturing Technology group.

Lucy Aitchinson is Engineering Director of Photon Energy. She has managed renewable energy installation projects for over fifteen years, including all of the technologies installed by Photon (PV solar panels, solar thermal and wind turbines). Lucy studied Electronic and Electrical Engineering at Birmingham University and is a Member of the Institute of Engineering Technology. She has worked in the solar PV industry since 1998.

Olga Malinkiewicz is co-founder and CTO at Saule Technologies. She is managing a team of 20 scientists from 11 countries working on the construction of the globally unique prototype production line for inkjet printed perovskite solar cells. She graduated from the Technical University of Catalonia in 2010 (MSc Photonics). In 2017 she obtained her PhD from the Institute of Molecular Science, University of Valencia at the group of Dr. Henk Bolink, with a thesis on low cost, efficient hybrid solar cells. Olga developed a novel perovskite cell architecture allowing fabrication of the efficient perovskite cells on PET.

Finlay Colville is the Head of Market Research at PV-Tech. He has more than a decade of experience tracking and commentating on the solar PV industry. Prior to this he held various sales and marketing roles with global equipment manufacturers. Dr Colville holds a BSc in physics and a PhD in non-linear photonics from the University of St Andrews.

Chris Case is the Chief Technology Officer at Oxford PV, a spin-out of Oxford University that is commercialising perovskites for PV applications. Most recently, he was the Chief Technology Officer for Linde Electronics and the former Chief Scientific Officer of The BOC Group. Earlier, he was engineering professor at Brown University and spent 10 years at AT&T Bell Labs. His talk will cover perovskite-silicon tandem cells that are being developed by Oxford PV.
