Large Area ITO-free Flexible White OLEDs with Orgacon™ PEDOT:PSS and Printed Metal Shunting Lines
SPIE
We demonstrate the feasibility of white organic light-emitting diodes that exclude the transparent conductor indium-tinoxide. Instead, a highly conductive OrgaconTM PEDOT:PSS material in combination with a metal support structure is used as transparent anode and hole-injection layer.

The project develops digital solutions for the design, manufacture and management of electronic components and end-of-life products. The project also includes testing in an appropriate industrial environment.
The aim is to develop sustainable methods, based on a circular model, to produce new high added value components and products by reusing semiconductors from different sources and supporting their remanufacturing.

EU Ecotron
A growing desire for continuous data collection, real time information and connectivity has resulted in an increased demand for electronic functionalities that are fully integrated in everyday objects, such as consumer electronics, healthcare, wearable electronics, IoT and smart packaging. Printed circuit boards (PCBs), commonly used to create electronic functions, are challenging to dismantle or recycle, and thus pose an ever-growing burden on our environment.
ECOTRON has accepted this…A growing desire for continuous data collection, real time information and connectivity has resulted in an increased demand for electronic functionalities that are fully integrated in everyday objects, such as consumer electronics, healthcare, wearable electronics, IoT and smart packaging. Printed circuit boards (PCBs), commonly used to create electronic functions, are challenging to dismantle or recycle, and thus pose an ever-growing burden on our environment.
ECOTRON has accepted this challenge and will develop new disruptive electronics manufacturing processes, technologies and materials with the ultimate aim to improve the sustainability of functional electronics. More specifically, ECOTRON will advance flexible, organic & printed electronics through a multidisciplinary approach involving bio-based materials, innovative (printing) processes, and device and module dismantling technologies. Not only that, but new recycling technologies will also be developed which will be the basis of a blueprint for a future recycling plant.

EU Unicorn
To reach climate targets, the EU must reduce its emissions from the transport sector. It is also important to improve the efficiency of our transport system and pave the way for zero-emission mobility. The EU-funded UNICORN project will increase the circularity-driven functional integration of electronics in automotive. It will do so by embedding eco-design principles and ensuring net beneficial effect on climate change mitigation. Specifically, the project will design and develop innovative…
To reach climate targets, the EU must reduce its emissions from the transport sector.

The EU-funded UNICORN project will increase the circularity-driven functional integration of electronics in automotive. It will do so by embedding eco-design principles and ensuring net beneficial effect on climate change mitigation. Specifically, the project will design and develop innovative green and circular technologies for automotive electronics. These include lightweight, low impact and bio-based materials, as well as the implementation for material circularity. UNICORN will establish a vision and roadmap to ensure functional electronics support EU mobility climate targets.
