“…By 2017, the PCE values had been optimized up to 3.74% for the OSCs built on highly flexible substrates with PEDOT:PSS anodes, whose conductivity was optimized through the morphology or conformational modifications of the polymer using effectively combined treatment and deposition methods. These methods included various pre-and post-treatment methods employing a diverse range of chemicals, such as the insertion of metal oxide HTLs between the polymer electrodes and the photoactive layers [23,68,106,107]. As the film surface morphology and chain arrangement of PEDOT:PSS are highly sensitive to the film deposition conditions, the choice of the right technique is crucial to obtain highly conductive and transparent electrodes.…”

“…This issue, along with PEDOT:PSS's other shortcomings, severely limits the device efficiency. Fortunately, the W f of PEDOT:PSS can be increased by simply using organic solvents like alkyl alcohol for the 'secondary doping' of the polymer, which enables higher hole extraction rates and leads to enhanced device performance [23].…”

“…In addition to its chemical and physical durability, the sufficiently stretchable [16,21] conductive polymer is also stable against environmental factors [13]. The feasible control over the material properties to adjust the electrical conductivity and transmittance through a simple PEDOT:PSS ratio adjustment, along with its solution processability and good-filmforming ability [13] and its work function (W f ) and film morphology tenability, makes it a ubiquitous substance that can be employed both as an active layer and as an electrode material for reproducible and practical device applications [22][23][24][25].…”

An organic conductive polymer, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT: PSS), is an attractive candidate for a low-cost, low-temperature, and solution-processed electrode material for achieving high-performance flexible and stretchable thin-film devices. Unlike most organic materials, this water-soluble conjugated polymer is highly stable against chemical and physical exposure. It exhibits the most superior mechanical flexibility and the highest optical transparency and electrical conductivity among all organic conductors. Therefore, this conductive polymer is among the most promising alternatives to the expensive, rigid, and brittle metal oxide-and even metal-based electrode materials, such as indium tin oxide (ITO) and gold, in the future solutionprocessed electronic devices. Nevertheless, the intrinsic conductivity of PEDOT:PSS is typically below 1 S cm −1 , which is too low for such devices. Fortunately, the material properties of PEDOT:PSS, including its conductivity, are easily tuned by employing a large number of simple approaches. In this paper, the reports on the successful application of PEDOT:PSS to a wide range of solution-processed organic devices, such as organic light-emitting diodes (OLEDs), organic thin-film transistors (OTFTs), and organic photovoltaics (OPVs), are reviewed. The recent progress in the development of highly conductive PEDOT:PSS-based films for electrode applications in the field of organic electronics is the main focus of the discussion herein.

Flexible thin-film organic semiconductor devices have received wide attention due to favorable properties such as light-weight, flexibility, reproducible semiconductor resources, easy tuning of functional properties via molecular tailoring, and low cost large-area solution-procession. Among them, ultraflexible electronics, usually with minimum bending radius of less than 1 mm, are essential for the development of epidermal and bio-implanted electronics, wearable electronics, collapsible and portable electronics, three dimensional (3D) surface compliable electronics, and bionics. This review firstly gives a brief introduction of development from flexible to ultraflexible organic semiconductor electronics, and design of ultraflexible devices, then summarizes the recent advances in ultraflexible thin-film organic semiconductor devices, focusing on organic field effect transistors, organic light-emitting diodes, organic solar cells and organic memory devices.

“…However, because an ITO thin film contains indium, a rare metal, depletion and insufficient supply of the resource have been concerns. Moreover, because an ITO thin film shows fragility to bending stress and because it is produced using the sputtering method, which requires high-temperature vacuum treatment, an ITO thin film cannot be used for developing flexible devices; instead, various materials, such as organic materials, metallic nanoparticles, and carbon nanotubes (CNT), have been studied [8]- [13]. In particular, organic materials are noteworthy because a film can be formed using a low-temperature process, and cheap devices can be manufactured by printing and coating [14] [15].…”

Flexible devices produced using organic materials have attracted the attention of many researchers. Important components of these flexible devices include transparent electrodes, which transmit visible light and possess conductivity. The present study improved the characteristics of a transparent conductive film that was made of poly(3, 4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), an organic conductive material, and that had been prepared using ink-jet printing. To improve the resistance value and visible light transmittance of the film, the film substrate was first cleaned with ultraviolet/ozone treatment, and then the film was annealed after it was deposited on the substrate and dipped into a polar solvent. Consequently, the resistance value of the thin film decreased. However, the surface state of the film changed according to the treatment method and affected its visible light transmittance. Thus, the surface state of the film substrate, the annealing temperature after film deposition, and the dipping treatment with a polar solvent influenced the characteristics of a thin film.
