Record efficiency for perovskite-based light-emitting diodes

Efficient near-infrared (NIR) light-emitting diodes of perovskite have been produced in a laboratory at Link√∂ping University. The external quantum efficiency is 21.6 percent, which is a record. The results have been published in Nature Photonics. The work is led by LiU scientist Feng Gao, in close collaboration with colleagues in China, Italy, Singapore, and Switzerland. … Continue reading Record efficiency for perovskite-based light-emitting diodes
