Organic Solar Cells, a commercial reality from lab to fab

Organic semiconductors are increasingly attracting the attention of the scientific community. However, they are considered to be too weak to ensure long-term stability and durability of the devices in which they are used. In this seminar, Associate Professor Guillaume Wantz will present his team's efforts in developing Pi-conjugated organic semiconductors that are can be cross-linked.

A major part of this presentation will focus on recent work on organic solar cells. Efficient bulk-heterojunction polymer solar cells require an interpenetrating network of electron donor and acceptor materials. however achieving optimum phase segregation can result in thermal instability. Associate Professor Wantz will show how his team has achieved versatile stabilisation of the morphology of bulk heterojunctions using cross-linkable additives blended in low amounts with polymer fullerene. Solar cells produced in this way have achieved stable performance after heating for days at low or high temperature. This seminar will display his team's latest results concerning stabilisation of interfaces and interlayers in such thin film solar cells, as well as progress on hybrid-perovskite solar cells and recent approaches towards robust hybrid fully covalent field effect transistors.


Guillaume Wantz obtained his Ingénieur degree (Masters) from the Graduate School of Chemistry and Physics of Bordeaux (ENSCPB) in 2001, including thesis work at Philips Research (Eindhoven, NL) on ink-jet printing. He received his PhD in Electronics Engineering from the University of Bordeaux in 2004 working on Polymer Light Emitting Diodes. He was Assistant Professor at the University of Bordeaux working on Organic Field Effect Transistors with research stays at Queen’s University, Canada. He has been an Associate Professor at the Bordeaux Institute of Technology since 2006. His research interest is on organic electronics with a focus on polymer photovoltaic solar cells, light-emitting electrochemical cells and the use of organic semiconducting single crystals. He was Invited Professor at Queen’s University in 2012 and at the University of Massachusetts in 2014. He has been a member of the Institut Universitaire de France in Paris since 2016. In 2017, he became an Associate Editor for the journal Materials Chemistry Frontiers. To date, he has published 105 research papers in peer-reviewed international journals and issued 7 patents (h = 28).
