The different water soluble ink-jet inks based on conjugated poly (3,4-ethylenedioxythioph ene):polystyrene sulfonate (PEDOT:PSS) were formulated with various organic co-solvents such as diethylene glycol (DEG), triethylene glycol (TRIEG), tetraethylene glycol (Tetra EG), and polyethylene glycol (PEG) to print on the flexible substrate. The effect of adding various organic co-solvents, which show a same trend of molecular weight, dipole moment and boiling point on the formulated inks properties and ink-jet printed films electrical conductivity, morphology and transparency were investigated. The conductivities of the ink-jet printed films were evaluated by four-point probe conductivity measurement. The morphologies of the printed films have been studied using atomic force microscopy and scanning electron microscopy. The size of PEDOT:PSS particles and the printed film morphology altered by addition of different types of co-solvent in the ink-jet ink formulation. The electrical conductivity of the ink-jet printed film increased by raising the molecular weight, boiling point and dipole moment of used co-solvent in ink-jet ink formulation.

“…It is clear that nowadays the mobility of small conjugated molecules outperforms that of amorphous silicon and these materials are now compatible with a large number of optoelectronic applications that do not require the high mobility typical of integrated circuits and processors. Organic optoelectronics devices can be fabricated using unconventional deposition methods such as inkjet [148], screen [149], and microcontact [150] printing. The low temperature required by these methods makes them fully compatible with plastic substrates and roll-to-roll processes [151].…”

In this review materials and technologies of the hybrid approach to integrated photonics (IP) are addressed. IP is nowadays a mature technology and is the most promising candidate to overcome the main limitations that electronics is facing due to the extreme level of integration it has achieved. IP will be based on silicon photonics in order to exploit the CMOS compatibility and the large infrastructures already available for the fabrication of devices. But silicon has severe limits especially concerning the development of active photonics: its low efficiency in photons emission and the limited capability to be used as modulator require finding suitable materials able to fulfill these fundamental tasks. Furthermore there is the need to define standardized processes to render these materials compatible with the CMOS process and to fully exploit their capabilities. This review describes the most promising materials and technological approaches that are either currently implemented or may be used in the coming future to develop next generations of hybrid IP devices.

“…However, ITO also has some disadvantages, such as the complicated production process (ITO is usually prepared by magnetron sputtering), the high price due to the lack of indium element, and relative brittleness, which is not suitable for flexible wearable devices. Therefore, there are other electrode materials developed for flexible optoelectronic devices, including poly (3,4ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) [7,8], silver nanowires/ nanomeshes [9,10], graphene [11], and carbon nanotubes [12]. Compared with the above mentioned electrode materials, PEDOT:PSS has good film-forming ability, high transparency, tunable conductivity, flexibility and solution processability, which can be prepared via spin coating [13], inkjet printing [14][15][16], dip coating [17], spray coating [18], etc.…”

Inkjet-Printed Highly Conductive Poly(3,4-ethylenedioxythiophene): Poly(styrenesulfonate) Electrode for Organic Light-Emitting Diodes

et al. 2021

Recently, inkjet printing technology has attracted much attention due to the advantages of drop-on-demand deposition, low-cost and large-area production for organic light-emitting diode (OLED) displays. However, there are still some problems in industrial production and practical application, such as the complexity of ink modulation, high-quality films with homogeneous morphology, and the re-dissolution phenomenon at interfaces. In this work, a printable poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS) ink is developed and obtains an adjustable viscosity. Finally, a patterned PEDOT:PSS electrode is fabricated by inkjet printing, and achieves a high conductivity of 1213 S/cm, a transparency of 86.8% and a uniform morphology without coffee-ring effect. Furthermore, the vacuum-evaporated and solution-processed OLEDs are fabricated based on this electrode and demonstrate a current efficiency of 61 cd/A, which is comparable to that of the indium tin oxide counterpart. This work confirms the feasibility of inkjet printing technology to prepare patterned electrodes and expects that it can be used to fabricate highly efficient optoelectronic devices.
