The mission of FADOS is to achieve targeted modification of semiconductor properties through electronic doping to control and modify its electronic characteristics. The project’s goal is to develop fundamental understanding and innovative fabrication processes to solve urgent problems in organic electronic devices, and enable new components with sustainable functionalities. Collaboration with industry partners will enhance the translation of research into real-world applications.

WP 4 Devices and Applications
OTFTs with ohmic contacts enabled by localized contacts doping; highly efficient OPVs thanks to doped charge collecting layers; highly efficient OLECs based on tuned pn-junction doping structures; multi-stimuli responsive neuromorphic OECTs; biomimetic spiking neuronal electrodes based on 3D shaped, p- and n-type hydrogels. In all cases, the operational stability of the doped devices and the industrial scalability of processes are additional objectives
