“…One solution of these problems is to prepare composite materials of AgNWs with graphene. [146][147][148][149][150][151][152][153][154] For example, graphene has been selected to work as the protection layer in a AgNW/graphene hybrid TCF, so that the stability of AgNWs/graphene hybrid TCE has been improved significantly thanks to protection of graphene.

The rising demands of optoelectronic devices, such as flexibility, stretchability, and energy efficiency, urgently require alternative transparent conductive films (TCFs) for indium tin oxide. Among all the candidates such as carbon nanomaterials, metal nanomaterials, conductive polymers, and other nanocomposites, graphene is highly promising because of its distinct properties, such as outstanding conductivity, impressive optical transparency, remarkable mechanical flexibility, and chemical/thermal stability. However, the practical application of graphene‐based TCFs (G‐TCFs) is still challenging due to the difficulty for preparing large‐area crystalline graphene with few defects for TCFs. Many efforts have been made to solve these problems, and several kinds of optoelectronic devices have been successfully fabricated with G‐TCFs. This review presents the recent development in this area made by the authors and others, including the material systems and synthetic strategies of G‐TCFs, as well as their applications as transparent electrodes in optoelectronic devices such as field effect transistors, organic light‐emitting diodes, organic solar cells, and other devices. The current major challenges in this area and the potential practical solutions are identified.

“…Silver nanowires (AgNWs) have also gained considerable research attention as potential candidates for transparent conductive electrode fabrication due to their competitive optoelectronic properties. [ 122 ] However, AgNW electrodes are easily oxidized, resulting in poor device performance and stability, [ 123 ] thereby limiting their choice. This problem has been addressed recently by integrating the AgNWs with graphene owing to the excellent stability and optoelectronic properties of graphene.…”

Recent advancements in technology have inevitably led to a significant increase in the global energy demand, whose traditional energy sources, such as fossil fuels and nuclear energy, are failing to meet needs due to their nonrenewable nature and consequent depletion. [1][2][3][4][5][6] Moreover, fossil fuels and nuclear energy are major sources of environmental pollution, which is responsible for unfavorable global warming and climate change. [7][8][9] Hence, there has been considerable research interest in sustainable and renewable energy sources, particularly solar energy, due to its natural abundance and environmentally friendly nature. [10][11][12] In this regard, solar energy is most commonly converted into electricity by making use of the first-generation solar cells, i.e., crystalline silicon solar cells, that are now commercially available, with high power conversion efficiencies (PCEs) of above 26% [13,14] and superior environmental stability. [15] However, the largescale production of silicon-based solar cells is restricted by their high production cost, complicated fabrication procedures, rigidity, [16,17] and PCE, which is almost close to the theoretical limit of %29.4%. [18] As a result, the second-generation solar cells, i.e., thin-film solar cells, such as amorphous silicon (a-Si) solar cells, copper indium gallium selenide (CIGS) solar cells, and cadmium telluride (CdTe) solar cells, [19][20][21] and the third-generation solar cells, such as organic solar cells (OSCs), perovskite solar cells (PSCs), and dye-sensitized solar cells (DSSCs), [22][23][24][25][26][27] have been developed by using simple and low-cost fabrication procedures. Among these, the thirdgeneration solar cells have gained significant research attention due to an abundance of low-cost materials, solution processability, flexibility, lightweight, environmental friendliness, and ease of scaling-up. [28][29][30][31][32] Interestingly, PSCs are a rising star owing to their recent breakthrough in PCE, which has shown a rapid increase from 3.8% in 2009 [33,34] to %25.5% for the current state-of-the-art PSCs. [35] The superior performance of PSCs is mainly attributed to the exceptional properties of metal halide perovskites, including the large absorption coefficient, direct and tunable bandgap, low exciton binding energy at room temperature, ambipolar charge transport characteristics, high charge carrier mobility, slow recombination kinetics, and long electron-hole diffusion length. [36][37][38][39][40][41] Thus, metal halide perovskites are emerging semiconductor materials, described by the general formula of ABX 3 , where A is a monovalent cation, such as methylammonium (CH 3 NH 3 þ ; MA), formamidinium (CH 3 (NH 2 ) 2 þ ; FA), caesium (Cs þ ), or rubidium (Rb þ ); B is a divalent metal cation, such as lead (Pb 2þ ), tin (Sn 2þ ), or germanium (Ge 2þ ); and X is a halide anion, such as iodide (I À ), bromide (Br À ), or chloride (Cl À ).

“…Metal nanowires, metal nanoparticles, conductive polymers and other conductive materials are also available. The salts of silver and copper are usually used to prepare metal nanowires and metal nanoparticles, but the preparation cost is high, and the conductive inks are easily affected by oxygen and moisture in the air, which is easy to deteriorate and seriously affect the conductivity 51 , 52 , 55 . The typical representative of conductive polymer is poly(3,4-ethylenedioxythiophene): poly(styrene sulfonate) (PEDOT:PSS).…”

Graphene oxide (GO), reduced graphene oxide (rGO) and carbon nanotubes (CNTs) have their own advantages in electrical, optical, thermal and mechanical properties. An effective combination of these materials is ideal for preparing transparent conductive films to replace the traditional indium tin oxide films. At present, the preparation conditions of rGO are usually harsh and some of them have toxic effects. In this paper, an SnCl2/ethanol solution was selected as the reductant because it requires mild reaction conditions and no harmful products are produced. The whole process of rGO preparation was convenient, fast and environmentally friendly. Then, SEM, XPS, Raman, and XRD were used to verify the high reduction efficiency. CNTs were introduced to improve the film conductive property. The transmittance and sheet resistance were the criteria used to choose the reduction time and the content ratios of GO/CNT. Thanks to the post-treatment of nitric acid, not only the by-product (SnO2) and dispersant in the film are removed, but also the doping effect occurs, which are all conducive to reducing the sheet resistances of films. Ultimately, by combining rGO, GO and CNTs, transparent conductive films with a bilayer and three-dimensional structure were prepared, and they exhibited high transmittance and low sheet resistance (58.8 Ω/sq. at 83.45 T%, 47.5 Ω/sq. at 79.07 T%), with corresponding $${{\sigma_{dc} } \mathord{\left/ {\vphantom {{\sigma_{dc} } {\sigma_{opt} }}} \right. \kern-\nulldelimiterspace} {\sigma_{opt} }}$$ σ dc / σ opt values of 33.8 and 31.8, respectively. In addition, GO and rGO can modify the surface and reduce the film surface roughness. The transparent conductive films are expected to be used in photoelectric devices.
