Printing of organic devices on large scale through roll-to-roll process

Stampa di dispositivi organici su larga area mediante processo roll-to-roll

Design

The TRIPODE public-private laboratory, through the ENEA Department NANO, has installed a laboratory dedicated to the study and the experimentation of organic electronic processes and devices on continuous flexible strip, for roll-to roll printing processes, and for other printing systems to fine tuning materials.

 

Description

Organic electronic products should take advantage of their innovative features, like being flexible, their big area, being super thin and lightweight, their eco-compatibility, and so on. To succeed in that, manufacturing processes must be easy and at a low cost, with extremely high performances and productivities and have a low or nearly zero environmental impact.
Starting from here, a laboratory has been installed dedicated to the study and development of optoelectronic organic processes and devices made with R2R techniques with a COATEMA Smartcoater system equipped with: gravure printing, rotary screen printing, slot-die coating, and doctor blade. Moreover, measurement devices of deposited thickness, a drying oven, the lamination of protective films on layers, and a cleaning station for layers before depositions are installed. The whole system is enclosed in a tight shell to keep it in an inert environment (nitrogen).

 

Market

The devices and systems manufacturing through continuous printing opens the way to the possibility to realize brand new and innovative products, in volumes maybe never obtained before, reaching hundreds of billions of pieces per year, and even more, of a single object (source: VTT). New type of light sources or of photovoltaic modules; display integrated in any object of day life; sensors of different type integrated together, and inserted in smart systems, to answer properly at the environment in which they are integrated or to the user, are few examples of the possibility that this technology might allow in few years (source: OE-A). Analysts foresee that the whole organic electronic and printed market, estimated in 20 billions of euro average in 2014, might reach 65billions of euro average in 2024 (source OE-A).

 

Industrial and productive sectors

Consumer electronic, flexible lighting (OLED); flexible solar photovoltaic (OPV); sensors; array of devices, even heterogeneous, interconnected (i.e. antennas).
