Abstract

In general, Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) is spin-coated as a hole transport layer in multi-structured quantum dots light-emitting diodes (QDLEDs). However, it is still a challenge to coat hydrophilic PEDOT:PSS on a hydrophobic layer in inverted QDLEDs. Electrohydrodynamic (EHD) jet printing was applied to make thin films from PEDOT:PSS solution on hydrophobic PVK film. The electrospray-deposited films showed precisely controllable thickness, scalability, and extremely low surface roughness (Ra of 0.55 nm). An inverted QDLED device (ITO/ZnO/QDs/PVK/electrosprayed PEDOT:PSS/Al) was prepared based on the understanding of electrospray droplets mechanism, the formation of PEDOT:PSS film on a PVK film, and drying dynamics of the inks. The device shows a current density of 3.7576 cd A−1, maximum luminance of 5692 cd m−2, and EQE of 2.2245%.
