A new joint Tel Aviv University (TAU) and Karlsruhe Institute of Technology (KIT) study published in Nature Communications on February 28 demonstrates remarkable continuous lasing action in devices made from perovskites.  Efficient near-infrared (NIR) light-emitting diodes of perovskite have been produced in a laboratory at Linköping University. The external quantum efficiency is 21.6 percent, which is a record. The results have been published in Nature Photonics.  Very recently, an NTU team lead by Assoc. Prof. Wang Hong, demonstrated high light extraction efficiency of perovskite photonic crystals fabricated by delicate electron-beam lithography.
