dc.description.abstractHighly transparent organic light-emitting diodes (TrOLEDs) are demonstrated using damage-free top cathodes of Cs2CO3/ Ag capped with ZnS layers. The presence of ultrathin Cs2CO3 layers not only improves the electron injection properties but also makes Ag thin films more continuous and uniform, resulting in ideal top electrodes with low sheet resistance and high transmittance. The combination of the uniform Ag morphology enabled by Cs2CO3 and the optimized thickness of ZnS capping layers results in TrOLEDs that have a peak transmittance as large as 80% with a luminous transmittance of 76.4%. These TrOLEDs exhibit a low turn-on voltage of 2.6V due to injection improvement by the Cs2CO3 layers. (C) 2011 Optical Society of America-
