A new method has been developed to fabricate high-performance polymer electronic devices using carbon-dot supported silver nanoparticles.

South Korean researchers have developed a single process for fabricating polymer light-emitting diodes (PLEDs) and polymer solar cells (PSCs) that, they say, remarkably increases their efficiency. The new method also shows great promise for producing polymer-based lasers.

This method, which involves carbon dot-supported silver (CD-Ag) nanoparticles, significantly enhances the outputs of polymer electronic devices. The effect of the nanoparticles is to reinforce the tiny electromagnetic fields within such devices to make them more energy efficient.

Reporting their results in Nature, the researchers – based at Ulsan National Institute of Science and Technology (UNIST) – say their method offers a versatile and effective way to create high-performance polymer electronic devices. Polymer devices are less expensive and easier to produce than current non-organic devices, such as gallium nitride (GaN) LEDs and silicon solar cells. Non-organic raw materials are also rarer than polymers.

While metal nanoparticles are thought to have great potential for improving the efficiency of semiconductors, there have been few examples, until now, of a single process that can enhance both PLED and PSC devices. What’s more, only basic equipment is required to create CD-Ag nanoparticles, while a low temperature, solution-based process adapts the method easily to both high volume mass production and to printed electronics.
