Graphene-based materials have been widely studied for the fabrication of electrodes in dye-sensitized solar cells (DSSCs). The use of graphene in the cathode is to reduce the amount of platinum (Pt), which in turn is expected to reduce the production cost of DSSCs. Additionally, in the structure of cathode, graphene acts as a supporting material to reduce the particle sizes of Pt and helps to maintain the high efficiency of DSSCs. For anodes, graphene can provide a more effective electron transfer process, resulting in the improvement of efficiency of DSSCs. In this chapter, the use of graphene-based materials for fabrication of cathodes and anodes in DSSCs, including platinum/reduced graphene oxide composite (Pt/rGO) and zinc oxide/reduced graphene oxide composite (ZnO/rGO) is discussed. The fabricated DSSCs were tested using current density-voltage (J-V) curves to evaluate the efficiency. The results of efficiency demonstrate that Pt/rGO is the potential material for fabrication of cathode in DSSCs, which helps to reduce the amount of Pt and maintain the high efficiency. The efficiency values of DSSCs fabricated from ZnO/rGO anodes show that the incorporation of reduced graphene oxide in the ZnO could improve the performance of DSSCs.

“…2D carbon nanomaterial graphene is under top of the considerable interest due to very interesting set of properties . Particularly, charge carrier mobility up to 350 000 cm 2 V −1 s −1 , charge carrier multiplication, flexibility, optical transparency, and chemical inertness can be mentioned . One of the main limitations preventing the wider application of graphene in semiconductor device technology is a complex graphene transfer procedure that is part of the catalyst‐assisted graphene deposition.…”

Herein, multiwavelength Raman spectroscopy studies of graphene samples synthesized directly on SiO2 and Si(100) substrates by microwave plasma‐enhanced chemical vapor deposition (MW PECVD), using five different excitation wavelengths in ultraviolet (UV), visible light, and near‐infrared (NIR) ranges, are presented paying attention to the peculiarities of the spectra. Raman spectra parameters are analyzed to reveal effects of the excitation wavelength. Structural features of graphene directly synthesized on SiO2 and Si(100) are discussed. Analysis of the interdependences of various Raman spectra parameters reveals that the most informative spectra are recorded using 532 nm wavelength excitation. Examination of the full width at half maximum values of G band (FWHM(G)) reveals that the graphene layers synthesized on Si(100) substrate consist of smaller crystallites comparing with SiO2 substrate.

“…[4][5][6] Therefore, a lot of attention has been paid to the preparation of monolayer graphene. [7] However, the innate zero bandgap of monolayer graphene limits its electronic application. [8] To successfully create bandgap, the stacked structures of graphene layers from bilayer to a few layers have been studied.…”

Due to the unique bandgap tunability of bilayer graphene, the preparation of large‐sized bilayer graphene has attracted a wide range of attention. Herein, the preparation of bilayer graphene, from stacking order to growth mechanism, is reviewed, and the chemical vapor deposition (CVD) of AB‐stacked bilayer graphene on copper substrate is emphasized. Various methods and growth strategies to synthesize bilayer graphene and the corresponding growth mechanisms are discussed. Mechanisms of layer‐by‐layer growth, the hydrogen passivation of graphene edges for the formation of bilayers, and carbon atoms penetrating through a copper wall for bilayer growth are included and highlighted for a better understanding of controlling bilayer graphene uniformity and forming its stacking order. Finally, the remaining challenges and the potential development of CVD‐controlled growth of bilayer graphene are outlined.
