Ito‐Free Flexible Electronics: Screen‐Printed Poly(3,4‐Ethylenedioxythiophene):Poly(Styrenesulfonate) Grids as ITO‐Free Anodes for Flexible Organic Light‐Emitting Diodes (Adv. Funct. Mater. 11/2018)

Thermally Activated Delayed Fluorescent Organic Light Emitting Diodes: Solution Processed to Printed

“…[ 59 ] Screen printing of the anode has been demonstrated for OLEDs in place of standard ITO anode. [ 79 ] Using printing to coat the anode allows printed TADF OLEDs to move away from the rigid and brittle ITO anode and creates the possibility for them to venture into stretchable/flexible/wearable electronics. [ 80 ] For cathodes, buffer materials, like LiF or Ba, are required to reduce their work function, which makes a fully printed TADF OLED a challenge.…”

Recent Technological Advances in Fabrication and Application of Organic Electrochemical Transistors

“…To date, screen‐printing is one of the most popular approach to large‐area deposition and has been widely utilized to prepare organic active layers for various applications such as solar cells, organic light emitting diodes (OLED), OFETs, and OECTs. [ 77–79 ] The printing mechanism is based on forcing the ink through a screen or mask by applying pressure with a squeegee and forming the patterned area (see Figure a). [ 57 ] Generally, the thickness of the printed layer relies on the thickness of emulsion of the screen and the viscosity of ink, which can be controlled in the range from hundreds of nanometers to several micrometers.…”

Benefits, Problems, and Solutions of Silver Nanowire Transparent Conductive Electrodes in Indium Tin Oxide (ITO)‐Free Flexible Solar Cells

“…Among them, hybrid electrodes comprising AgNWs‐graphene oxide (GO) and AgNWs‐mono layer graphene (MLG) from CVD have been widely investigated and applied to numerous optoelectronic devices. [ 15–167 ] As shown in Table 4, significant surface‐roughness reduction by applying these materials is achievable. The GO dispersion induced...…”
