Organic electronic device to replace silicon-based electronics

An organic electronic device in which a charge generated by light lived approximately 10,000 longer than was previously thought possible has been developed by an international research team.

The scientists created a small device based on organic molecules in which the built-in electric field created a well that trapped and protected charge carriers.

This opens up the possibility of creating entirely new classes of organic electronic devices such as ultra-sensitive photo detectors to image distant stars or flexible memory elements, which could be used in wearable computers, according to the researchers.

Although silicon-based chips and transistors have been at the heart of all electronic devices for more than half a century, there is an increasing interest in transitioning away from silicon-based electronics to new organic devices.

Just like living organisms, organic electronics use carbon in complex molecules as their key functional component, which make them less expensive, more environmentally friendly and easier to recycle than the older ones.

One of the most commercially successful organic electronic devices is OLEDs found in smartphone displays.

Researchers from the University of Cologne in Germany have advanced the method that significantly prolonged the lives of charges in organic electronic devices in collaboration with researchers from Jilin University, China and the University of Nottingham, UK.
