New publication

Sung-Doo and Wenhao’s paper reporting highly efficient perovskite NIR LED has been published in Nature Communications. We demonstrate a grain engineering methodology that combines solvent engineering and heterostructure construction to improve light outcoupling efficiency (to ~ 40%) and defect passivation. The resulting near-infrared perovskite light-emitting diodes achieve a peak external quantum efficiency of 31.4% and demonstrate a maximum brightness of 929 W sr−1 m−2. These findings indicate that perovskite light-emitting diodes have potential as cost-effective, high-performance near-infrared light sources for practical applications. Read the story here.
