Insitute for Materials Research, Hasselt University
Prof. Dr. Koen Vandewal (23-06-1981) obtained his PhD in Physics at Hasselt University in 2009 under the supervision of Prof. Dr. Jean V. Manca, working on the physics of organic photovoltaics. After that, he has been working for two years as a Postdoctoral Fellow at Linkoping University in Sweden and another two years at Stanford University in the US.
In 2014, he was appointed as Endowed Professor at the Technische Universitaet (TU) Dresden in Germany, where he led a research group which aimed to solve fundamental questions in the field of organic and molecular electronics with relevance to applications in opto-electronic devices such as organic light-emitting diodes, organic solar cells and sensors. In January 2018, Prof. Vandewal took a position in Insitute for Materials Research, Hasselt University.
In the organic electronics community he is best known for his seminal work on charge-transfer states at organic interfaces and their role in photovoltaic devices.
Most photovoltaic technologies exhibit high photon-to-charge-carrier conversion yields, approaching 90%-100%. However, a solar cell only generates power when an additional photo-voltage is produced. This photo-voltage is ideally as close as possible to the open-circuit voltage (Voc) of the device.
