Printing technology is set to enable the high-throughput low-cost and customized fabrication of optoelectronic and sensors devices. For this goal to become a reality, this functional printing approach should encompass a material process development which enables high device performance and industrial compatibility, thus enabling a facile transfer of research results into consumer applications. In the first part of this talk, I will present the fabrication of fully printed organic photodiodes (OPDs) by digital printing techniques (e.g. aerosol and inkjet). The devices show mechanical flexibility, semitransparency and an excellent reproducibility. Furthermore, I will discuss the use of the ink formulation as way to access and tailor material optoelectronic properties and our recent efforts in the fabrication of inkjet printed OPDs based on novel non-fullerene acceptors (NFAs). In the second part of the presentation, I will discuss our recent efforts in employing biocompatible and biodegradable materials as passive and active components of printed light-emitting devices and displays.
