Stable perovskite LEDs one step closer

Researchers at Linköping University, along with colleagues in Great Britain, China and the Czech Republic, have developed a perovskite light-emitting diode (LED) with both high efficiency and long operational stability.

Perovskites are a large family of semiconducting materials that have aroused the interest of scientists around the world. Most progress has been made in research into the use of perovskites in solar cells, but they are also well-suited for the manufacture of LEDs.

Light-emitting diodes based on perovskites are still not sufficiently stable for practical use, but the researchers have brought them one step closer.
