Researchers design a novel cathode structure for top-emitting OLEDs, enabling a 10 fold increase in efficiency

Researchers from the Russian Academy of Sciences and the Moscow Polytechnic University have developed a new top-emitting OLED device, that is based on a novel cathode design. The new cathode enables a 10-fold increase in power efficiency compared to conventional Mg:Ag cathodes. The new cathode is based on a Mg:Ag/Ag structure, that combines a 1 nm Mg:Ag layer with a 9nm Ag layer. The researchers say that this design ensures minimal optical losse…
