Light-emitting electrochemical cell (LECs)- now an efficient and bright device

An efficient and bright device.


Researchers from Umeå University and Linköping University have developed light-emitting electrochemical cell (LECs) that emit strong light at high efficiency. Accordingly, the thin, adaptable and light-weight LEC guarantees future and enhanced applications inside home diagnostics, signage, brightening and human services.

The light-producing electrochemical cell (LEC) can be thin, adaptable, and light-weight and be headed to basically any outflow shading by the low voltage of a battery. It can likewise be amazingly eased since it can be manufactured with ease printing and covering strategies like how daily papers are created.

Up until now, a constant and risky downside has been that it has not been conceivable to achieve solid shine at high productivity from LEC gadgets. Truth be told, it has been addressed on general grounds whether the LEC is even equipped for being all the while brilliant and proficient.

In the present issue of Nature Communications, a group of researchers from Umeå University, Linköping University, and the organization LunaLEC AB in Sweden show a way towards settling this issue.

Utilizing a methodical blend of trials and recreations, they have built up a nonspecific arrangement of outline standards, including adjusted trap profundities, streamlined doping, and electrochemically stable materials. The specialists’ approach has made ready for LEC gadgets that transmit light with a high splendor of 2,000 disc/m2 at an electron-to-photon effectiveness of 27.5 percent.

Ludvig Edman, leader of the project said, “As a point of reference, a normal TV operates between 300 to 500 cd/m2, while 2,000 cd/m2 is the typical brightness of an OLED illumination panel. Concerning efficiency, our LEC device is close to that of a common fluorescent tube.”

“With this performance, the LEC component is now not only offering low costs and highly attractive design advantages but is also becoming a true competitor with existing technologies, such as the fluorescent tube, LED and OLED, as regards to efficient and practical operation.”

The results are published in Nature Communications.
