Koen Vandewal

Koen Vandewal is Full Professor and Chair of Physics at Hasselt University (Belgium), where he leads the Organic Optoelectronics research group. He obtained his PhD in Physics at Hasselt University in 2009, followed by postdoctoral positions at Linköping University (Sweden) and Stanford University (USA). Before joining Hasselt in 2018, he held an endowed professorship at TU Dresden (Germany).

His research solves fundamental questions in organic, hybrid and molecular electronics for applications in devices like OLEDs, solar cells, and sensors. Key research themes include:

• Organic photovoltaic physics and material stability
• Light-matter interactions in optical microcavities
• Nanoscale assembly of donor-acceptor systems
• Advanced characterization of quantum dot photophysics

Recent publications focus on overcoming efficiency limits in transparent photovoltaics, understanding excitonic disorder in organic semiconductors, and developing printed sustainable transistors. He has supervised numerous PhD students through the OOE research group.
