Session 7: FPE Manufacturing Facilities
Printed Electronics at CDT

8:00 AM - 8:25 AM
The field of printable electronics is enabling a large range of electronic components to be made from solution based materials and printing methods, thus allowing for flexibility in design, functionality, form factor and the scaling of their respective application. CDT continues to pursue and develop a wide range of these applications including flexible displays, OLED lighting, photodetectors, gas- and biosensors and energy harvesting and storage.
In this talk we will give a general overview of the status of our technologies. We will give special emphasis to our flexible OLED display, energy harvesting and storage solutions. Recent advances in our printed flexible OLED technology has enabled a lower voltage platform (5V) without requiring a low work-function cathode. We have also developed the processes to be compatible with short TACT times. These RGBW devices have lifetimes in excess of 2000 hrs, and we have demonstrated a shelf life greater than 5 years with a low cost lamination encapsulation solution. Additionally, the potential for such devices in consumer products such as white goods, have been confirmed by increasing the print area and integrating the flexible OLEDs with NFC and touch technologies.
The work on energy solutions is motivated by the ever increasing demand for thin and flexible energy harvesting and storage devices which in turn is fuelled by the need to power the Internet-of-Things (IoT) and the emerging field of wearable electronic devices. We will present our roadmaps and recent advances in printable thermoelectric generators (TEGs) and energy storage (ES) devices. More specifically, in terms of printable TEGs, our technology offers inherently good process-ability, low toxicity and suitability for printing techniques required for mass manufacture. We will discuss recent progress on device development and the n-type thermoelectric materials that have has thus-far remained a challenge. We will also show progress in tuneable hybrid ES devices that combine supercapacitor with battery properties on a non-toxic and heavy metal-free materials platform that can be processed from solution to enable facile integration with other devices. Specifically we will report that by using non-aqueous electrolytes, we have demonstrated tuneable voltages in the range of 2-3V.
Miguel holds an MSc (Hons) in Solid State Physics and Electronics from the University of Sevilla, Spain, and a PhD in Physics from the University of Hull, UK where he studied Liquid Crystal Polymer Networks for Photovoltaics applications. At CDT Miguel is responsible for the R&D development in the area of lighting and energy harvesting and storage applications. Prior to that Miguel lead a research group at NPL in London working on electrical metrology and novel applications with graphene. Previous position include Merck Chemicals ltd and also at Hewlett Packard Labs in the UK where Miguel occupied a variety of roles in OPV and OTFT technologies.
