Electrochromic technology capable of producing three colors—yellow, green, and blue—from a single material using only a solution process, without the need for expensive vacuum equipment, has been developed by domestic researchers. It is expected to contribute to the localization of materials in the fields of energy-saving smart windows and next-generation color displays.

The Korea Institute of Materials Science announced on the 6th that it has succeeded in developing core material technology for solution-process-based multicolor electrochromic smart windows.

This research was conducted by a team led by Principal Researcher Kim So-yeon of the Energy and Environmental Materials Research Division, and it is reported that a single material can rapidly and stably switch between three colors through voltage control.

The manufacturing of conventional electrochromic materials required expensive vacuum equipment, which limited large-area application and mass production.

The researchers explained that because the newly developed technology is based on a solution process, large-area fabrication is possible without vacuum equipment.

It is also known to have fast color switching speed and excellent durability.

The researchers stated that this technology can be applied to the fields of energy-saving smart windows and next-generation color display materials.

In particular, the researchers predicted that the localization of the material would contribute to reducing dependence on imports and securing export competitiveness.
