Development of scalable perovskite nanocrystals coating technology   Research team at Seoul National University (Prof. Tae-Woo Lee) developed highly efficient large-area perovskite light-emitting diodes (PeLEDs) with an external quantum efficiency (EQE) of 22.5% and pixel size of 102 mm2. The research results were published in Nature Nanotechnology, which is the world-renowned international academic journal, on May 4th (Title: Exploiting the full advantages of colloidal perovskite nanocrystals for large-area efficient light-emitting diodes).   ...
