We herein report an investigation of the device performance capabilities and impedance characteristics of solution-processed organic light-emitting devices (OLEDs) with all-water-processable triple-stacked hole-selective layers (HSLs) on an indium-tin-oxide (ITO) anode, fabricated using a simple coating technique. Highly smooth and homogeneous triple-stacked layers were deposited via horizontal-dip- (H-dip-) coating using aqueous dispersions of graphene oxide (GO), molybdenum oxide (MoO 3 ), and poly(ethylenedioxy thiophene):poly(styrene sulfonate) (
