“…Of these materials, graphene is arguably the leading 2D material, which, despite its lack of a bandgap, was also quickly proposed as a potential transparent conductor. [98,99] A monolayer of graphene can have carrier mobilities above 10 000 cm 2 V −1 s −1 . [33] So far, such carrier mobility was achievable only in nanometer-scale, free-standing graphene flakes, obtained by mechanical exfoliation, and on films grown by chemical vapor deposition (CVD) on boron nitride substrates.…”

With the development of new generations of optoelectronic devices that combine high performance and novel functionalities (e.g., flexibility/bendability, adaptability, semi or full transparency), several classes of transparent electrodes have been developed in recent years. These range from optimized transparent conductive oxides (TCOs), which are historically the most commonly used transparent electrodes, to new electrodes made from nano‐ and 2D materials (e.g., metal nanowire networks and graphene), and to hybrid electrodes that integrate TCOs or dielectrics with nanowires, metal grids, or ultrathin metal films. Here, the most relevant transparent electrodes developed to date are introduced, their fundamental properties are described, and their materials are classified according to specific application requirements in high efficiency solar cells and flexible organic light‐emitting diodes (OLEDs). This information serves as a guideline for selecting and developing appropriate transparent electrodes according to intended application requirements and functionality.

“…Particles are prepared by pyrolysis of suitable precursors (e.g., Fe(CO) 5 ) at low temperature in range 300-1200 °C. One of the drawbacks of the method is high defect density in the material owing to low synthesis temperature compared to arc discharge and laser ablation methods.…”

“…These drawbacks have led to increasing the research attention to searching the indium-free TCF. Recently, graphene [3][4][5][6] and CNTs (CNT) [7,8] have emerged as promising In-free candidates to be used as transparent and conducting materials [9]. Studies and applications of graphene as a TCF in photovoltaic technology [10][11][12][13][14], e.g.…”

“…However, ITO also suffers from some disadvantages such as high production costs, limited indium resources, and ion diffusion into polymer layers. 145 In particular, ITO cannot be used for flexible devices because it is mechanically rigid and brittle. Several well-developed high-performance ITO alternatives, such as single-walled CNTs or metal nanowires, are also expensive.…”

Graphene has wide potential applications in energyrelated systems, mainly because of its unique atom-thick twodimensional structure, high electrical or thermal conductivity, optical transparency, great mechanical strength, inherent flexibility, and huge specific surface area. For this purpose, graphene materials are frequently blended with polymers to form composites, especially when fabricating flexible devices. Graphene/polymer composites have been explored as electrodes of supercapacitors or lithium ion batteries, counter electrodes of dye-sensitized solar cells, transparent conducting electrodes and active layers of organic solar cells, catalytic electrodes, and polymer electrolyte membranes of fuel cells. In this review, we summarize the recent advances on the synthesis and applications of graphene/polymer composites for energy applications. The challenges and prospects in this field have also been discussed. V C 2012 Wiley Periodicals, Inc. J. Polym. Sci., Part B: Polym. Phys. 2013, 51, 231-253 KEYWORDS: composites; energy; fuel cell; graphene; lithium ion battery; redox polymers; solar cell; supercapacitor; synthesis INTRODUCTION Energy is one of the most important recent topics of concern to human society. To replace conventional fossil fuels, clean and renewable energies based on sunlight, wind, new chemicals, and biofuels are urgently demanded. Therefore, materials that can directly convert or store renewable energies are being extensively studied. Among them, graphene has recently attracted a great deal of attention because of its unique atom-thick two-dimensional (2D) structure 1,2 and excellent electrical, 2 thermal, 3 optical, and mechanical properties. 4,5 Graphene is a promising material for applications in various energy-related systems such as supercapacitors, 6-9 secondary batteries, 10-14 solar cells, 15-17 and fuel cells. [18][19][20] For this purpose, graphene materials are frequently blended with polymers to form functional composites. [21][22][23] The polymer component can improve the processability and/or flexibility of graphene materials, and also possibly provide them with new functions. To date, various graphene composites with insulating or conducting polymers (CPs) have been prepared through noncovalent 22 or covalent approaches. 24 They have also been applied as electrodes for supercapacitors and lithium ion batteries (LIBs), 25-29 counter electrodes of dye-sensitized solar cells (DSSCs), 15,30,31 and transparent conducting electrodes (TCEs) 32,33 or active layers of organic solar cells, 34 catalytic electrodes, and polymer electrolyte membranes of fuel cells. [35][36][37] This review focuses on summarizing the recent advances in the synthesis of graphene/polymer composites and their energy applications.
