Swedish researchers have developed a new, environmentally friendly way to create conductive inks for use in organic electronics such as solar cells, artificial neurons, and soft sensors. The findings, published in the journal Nature Communications, pave the way for future sustainable technology. Here is the articlehttps://www.nature.com/articles/s41467-023-44153-7
Organic electronics are expected to replace traditional silicon-based electronics. The new semiconductors are highly flexible, and their low weight combined with the better electrical properties giv them applicability for energy storage, solar cells sensors, and soft implants.
Organic electronics are made from special semiconducting plastics, known as conjugated polymers.
Researchers at the Linköping University have developed a new sustainable method for processing these polymers from water. In addition to being more sustainable, the new inks are also highly conductive.
“Our research introduces a new approach to processing conjugated polymers using benign solvents such as water. With this method, called ground-state electron transfer, we not only get around the problem of using hazardous chemicals but we can also demonstrate improvements in material properties and device performance,” says Simone Fabiano, senior associate professor at the Laboratory of Organic Electronics.
