From ink formulations to printed hybrid devices

Abstract :

The formulation of an ink is greatly determined by the printing process which transfers the ink onto a substrate.
Most importantly, the deposited materials need to maintain their desired functionality, but printing also offers the opportunity to self-assemble materials such that new properties arise.
Here, latest success stories in printed electronics merged the field of organic semiconductors with solution processable inorganic systems. An improvement in performance of a wide range of opto-electronic devices is expected.
We give examples of hybrid devices that exploit the adaption of ink formulations (2D materials, metal oxides, organic dyes) for the most suitable processing tool.

Jakob Heier received a Diploma in Physics from University of Konstanz, Germany, and a PhD in Materials Science and Engineering from Cornell University, USA. He has been holding positions in Academia and Industry.
Today, Jakob Heier is leading a research group in the Laboratory of Functional Polymers at Empa, where he is heading the wet coating and printing activities in the Coating Competence Centre (CCC). In his research, he investigates self-assembly of organic and inorganic materials in thin films, and exploits these principles for functional large area coatings and devices.
