Design of organic semiconductors

Organic semiconductors are intensively investigated for many applications, including displays and lighting, energy conversion, sensors and electronics. While inorganic semiconductor devices and integrated circuits are routinely designed on all levels and even tested using computational tools, the modeling methodology for their organic counterparts has yet to reach this level of maturity. In our project a consortium of experimental and theoretical groups will make crucial steps towards the development of an integrated and predictive computational model for organic devices, in particular for OLED, organic photodetectors and solar cells and thermoelectric generators. On the basis of this model we will -as a first example address outstanding experimental challenges for two classes of devices: Firstly, the energy efficiency in OLEDs and secondly, we will elaborate on the materials design for organic thermoelectric generators.
