New Development for Electrochromatic Devices

WRITTEN BY: Nouran Amin

Scientists have developed a new approach for foldable and solid devices—best known as solid and flexible electrochromic (EC) devices, such as wearable electronics and smartphones. A unique aspect of EC devices are in fact the color or opacity of the material that changes when applying a voltage.

Previously, electrochromic devices use indium tin oxide (ITO) electrodes.

"With all these limitations, the need for ITO-free optoelectronic devices are considerably high. We were able to achieve such a goal," says Dongling Ma who led the study recently published in the journal Advanced Functional Materials.

"We reached high stability and flexibility of transparent conductive electrodes (TEC), even in a harsh environment, such as oxidizing solution of H2O2" she adds. They are the first to apply stable nanowires-based TCEs in flexible EC devices, using silver nanowires coated with a compact gold shell.
