“…We assume that the PEDOT:PSS thin lm, which acted as conducting layer on the graphene lm, effectively prevented further damage to the lm. 41,42 In the case of the Seebeck coefficient, both the graphene lm and hybrid lms exhibit a small variation of bending test, as shown in Fig. 6(b).…”

Poly(3,4-ethyldioxythiophene):poly(styrene sulfonate) (PEDOT:PSS), as an thermoelectric(TE) material, exhibits a high electrical conductivity and ZT value (10 À1 -10 0 ). Nevertheless, a low thermovoltage of the organic thermoelectric materials must be overcome, in comparison to that of semi metals. Recently, to address these challenges, several researchers have investigated PEDOT:PSS/carbon material composites.Herein, a transparent and flexible hybrid film made up of rapid thermal chemical vapor deposition (RTCVD) graphene and PEDOT:PSS results in enhanced TE performance. The PEDOT:PSS was synthesized by oxidative polymerization, and the hybrid process of the graphene film and PEDOT:PSS film was conducted using the layer-by-layer method. The results of AFM and Raman spectroscopy revealed that the synergistic effect through composite films improved the electrical properties. The maximum electrical conductivity and power factor of the RTCVD graphene/PEDOT:PSS (RCG/P) hybrid film were 1096 S cm À1 and 57.9 mW m À1 K À2, respectively. In addition, the RCG/P hybrid film exhibited excellent mechanical flexibility and stability.

“…12,17,36,143,144 To achieve high electrical conductivities, some conductive polymers, such as polyaniline, polypyrrole, and polythiophene, have been developed with the addition of suitable chemical dopants. Among these, PEDOT:PSS is one of the most successful and widely used conducting polymers for optoelectronic applications, especially for those in organic-based devices.…”

Transparent electrodes for organic optoelectronic devices: a review

Abstract. Transparent conductive electrodes are one of the essential components for organic optoelectronic devices, including photovoltaic cells and light-emitting diodes. Indium-tin oxide (ITO) is the most common transparent electrode in these devices due to its excellent optical and electrical properties. However, the manufacturing of ITO film requires precious raw materials and expensive processes, which limits their compatibility with mass production of large-area, low-cost devices. The optical/electrical properties of ITO are strongly dependent on the deposition processes and treatment conditions, whereas its brittleness and the potential damage to underlying films during deposition also present challenges for its use in flexible devices. Recently, several other transparent conductive materials, which have various degrees of success relative to commercial applications have been developed to address these issues. Starting from the basic properties of ITO and the effect of various ITO surface modification methods, here we review four different groups of materials, doped metal oxides, thin metals, conducting polymers, and nanomaterials (including carbon nanotubes, graphene, and metal nanowires), that have been reported as transparent electrodes in organic optoelectronic materials. Particular emphasis is given to their optical/electrical and other material properties, deposition techniques, and applications in organic optoelectronic devices.

“…Using such an approach, thin films of PEDOT:PSS have been deposited via scalable techniques such as blade coating, [5,6,7] spray coating, [8][9][10][11][12] or gravure printing. [13,14] Unfortunately the use of techniques such as multi-pass deposition or the incorporation of surfactants can result in a reduction in performance of the PEDOT:PSS film deposited, such as reduced conductivity, low surface uniformity, the creation of thicker films (and thus reduced optical transparency), or spatially non-uniform work function. [15][16][17] For many applications in printable electronic devices, control over optical and electronic properties is critical in order to optimise device performance and efficiency.…”

Such films can be deposited using a single pass in the wet phase without the use of surfactants; a process that greatly simplifies their deposition. Using this technique we create films having thickness and roughness comparable to that of spin coated films, whilst properties such as the conductivity and stability can be improved.
