The Research Division ‘Complex Materials and Devices’ focusses on innovative device concepts which are made possible by the specific properties of the active material(s) from which they are built.

  The main functionality in which we are interested is the conversion of sustainable sources of energy, like sunlight or heat, into electricity. The devices employed for this range from organic photovoltaic solar cells to thermoelectric generators and ratchets. Other innovative, funny or even outlandish devices have our interest too – e.g. organic ferroelectrics.

  In the materials and devices of our interest typically many different length and energy scales play a role, starting at nanometers and millivolts and ranging to more tangible sizes and energies. Phenomena at different scales are typically related and often properties at some small scale give rise to beautiful and unexpected emergent behavior at a (much) larger scale. The outcome of this interplay is the device functionality. The complexity gives many opportunities to create and optimize device functionality, but also forms a rich and rewarding playground for fundamental science.


The active materials we work with are mainly organic semiconductors, used either as single material but also in layered stacks and (partially) phase-separated mixtures.

This research division has been initiated in 2014, hence we are in a build-up phase. More content will be added over time!
