Efficient and stable hybrid perovskite-organic light-emitting diodes with external quantum efficiency exceeding 40 per ... - EurekAlert


Tandem LEDs offer an effective way to integrate different light-emitting technologies for better display that meets Rec. 2020 color gamut standard. Towards this goal, Scientist in China developed a stable, efficient and high-color purity green LED with a tandem structure by combining perovskite LED and organic LED technologies. The key to achieving this result is to design an efficient interconnecting layer with p-type interface doping that provides good opto-electric coupling and reduces Joule heating.
