Aerosol jet printed AgNW electrode and PEDOT:PSS layers for organic light-emitting diode devices fabrication

Aerosol jet printing is a cutting-edge technology offering a plethora of advantages in organic optoelectronics fabrication. In this work, we fabricated organic light-emitting diodes on glass substrates. Silver nanowires (AgNWs) and poly (3,4-ethylene dioxythiophene) polystyrene sulfonate (PEDOT:PSS) were aerosol-jet printed as the bottom electrode and hole transport layer, respectively. The other remaining layer materials were blade coated to form a multi-layered structure of the devices. The results show that the organic light-emitting diode device with similar to 40 mm(2) active areas was successfully obtained. A comparison study of blade-coated organic light-emitting diode devices on indium tin oxide based electrode is also discussed. The results of this work show that aerosol jet printing technology enables fully solution-based fabrication of organic light-emitting diode devices.
