By simply pre-depositing an ethanol layer, a series of procedures including homogenization, solvent exchange, post-stretching, and air drying would take place, leading to uniform deposition of graphene nanosheets with a denser structure. In this paper, we innovatively demonstrate a novel and facile pre-deposition assisted strategy for inkjet printing of graphene ink. However, the huge challenge associated with inkjet printing of graphene-based inks is to overcome the coffee ring effect, which results in ununiformity of the printed pattern. Inkjet printing of graphene-based materials represents a highly promising deposition method, as benefits of its flexibility for graphical printing and simple operation process. The description of this method can be used to obtain efficient printed OLEDs both in academic and in industrial settings. Our contribution provides a complete framework for inkjet printing of high quality Super Yellow films for OLEDs. We checked that, the values of mobility of the charge carriers in the printed films, measured by transient electroluminescence, are similar to the values of mobility measured in spin coated films. Fabricated OLEDs have shown a remarkable characteristics of performance, similar to the OLEDs fabricated by means of spin coating technique. Optimization of ink composition and printing resolution were performed, until good quality films suitable for OLEDs were obtained. We develop the formulation of Super Yellow ink, containing non-chlorinated solvents and allowing stable jetting. In this work, we use the inkjet printing technique to investigate the formation of thin active layers of well-known light emitting polymer material: Super Yellow (poly(para-phenylene vinylene) copolymer). The above approach enables upscaling of the OLEDs fabrication process which, as a result, would become faster than conventionally used vacuum based processing techniques. Inkjet printing technique allows manufacturing low cost organic light emitting diodes (OLEDs) in ambient conditions. The shelf stability is also tested and after seven months, the all solution-processed encapsulated OLED keeps 82% of its initial EQE. The all-solution processed top-emitting OLEDs reach high luminance (7 000 cd m-2) and an efficiency close to reference devices with evaporated electrodes: 4.2 cd A-1 vs 7.6 cd A-1, respectively. As the top electrode, a conductive PEDOT:PSS formulation easily processable on organic layers due to a low contact angle is utilized. Ink-jet printing provides the advantages of a mask-free patterning and a non-contact manufacturing.

In this work, we investigate all-solution processed OLEDs based on ink-jet printed silver bottom electrodes and spin-coating of all other layers. While the research in the photovoltaic field has developed R2R printed large-scale solar modules, the research in solution-processed OLEDs is not as far yet. Roll-to-roll (R2R) printing and coating techniques can be the answer to a low cost and large-area mass production for organic electronics devices. In order to use the OLEDs for on-chip fluorescence sensing applications, the operational lifetime was also tested under high emission brightness of ~10 000 cd/m². High emission brightnesses of 50 000 cd/m² and 16 000 cd/m² were achieved under voltage-pulsed driving mode on ITO and silver nanowire embedded PEDOT:PSS bottom electrodes, respectively. It is the first ITO-free, vacuum-free, fully solution-processed transparent OLED using inkjet printing technique as the exclusive technique for electrode deposition and patterning. In this contribution, we introduced an ITO-free, inkjet-printed transparent OLED with a simple 4-layer structure via an inkjet-printable Al:ZnO:PEI interlayer. However, a complex layer structure consisting of ultrathin layers is typically required to obtain high device performance, which is difficulty for inkjet printing manufacturing due to the interlayer mixing, limited layer uniformity, and limited materials availability. Furthermore, digital printing techniques such as inkjet printing provide the advantages of mask-free patterning, non-contact manufacturing and direct chip-integration. Solution processing manufacturing is the key method to reduce the OLED device production cost.
