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 losses, and enhanced electron injection while maintaining high conductivity.
The new device reached an efficiency of 107lm/W, a 10 fold increase compared to conventional devices that reached 11 lm/W.
