Especially, when a similar to10 nm-thick polystyrene layer was employed, the device gave two orders of magnitude higher external quantum efficiency than that of the one without an insulating nanolayer This enhancement may result from the dramatic lowering of the effective barrier height for electron injection to the emitting layer.
