Inkjet-Printed organic Photodetectors for Imaging Applications (IPPIA)
Start date: Sep 1, 2011, End date: Aug 31, 2014 PROJECT  FINISHED 

"The recent development of a wide range of solution processable functional materials, especially organic semiconductors and highly conducting metal inks, and the broad availability of graphical arts printing technologies are at the base of a revolution which will lead to the fabrication of organic opto-electronics devices by means of high-throughput, inexpensive mass production processes. Additive printing techniques offer in fact advantages in terms of process simplification, layer-to-layer alignment, compatibility with large areas, and potential cost reduction compared to subtractive lithographic patterning. In particular inkjet, which is a non-contact technique, offers high flexibility and is compatible with a large range of functional materials. It is particularly advantageous when controlled volumes of inks have to be placed in precise positions on a substrate, as for example in the case of organic photodetectors (OPDs). The possibility to tune OPDs responsivity, therefore enabling a selective photodetection, and to deposit them in principle on substrates of any kind and shape, make them very appealing for various advanced applications.Project IPPIA aims to demonstrate inkjet printed OPDs sensitive to the visible spectrum of light, suitable for imaging applications. Dr. M. Caironi will be responsible of this scientific activity, which will take place at the Italian Institute of Technology (IIT), a leading research center in Italy. The final objective of this project is to fabricate small arrays of an organic active pixel by integrating OPDs with suitable organic field-effect transistors, acting as an electrical switch, thus paving the way for cost-effective, light-weight, conformable digital imagers. The expertise of Dr. Caironi in the field, and the infrastructures and complementary expertise available in IIT have a great potential for a successful project and for increasing the overall scientific and technological competitiveness of the European community."
