“…Therefore, injection FCCVD has been proved to be an effective method for CNT synthesis. [32,[42][43][44][45] It is wellknown that the physical and chemical properties of SWCNTs are closely related to their diameters. Therefore, considerable effort has been devoted to controlling the size of catalyst particles and hence, the diameter of the grown SWCNTs.…”

Floating catalyst chemical vapor deposition (FCCVD) has been one of the most important techniques for the synthesis of high-quality single-, double-, and multi-wall carbon nanotubes (CNTs). The method is characterized of simple processing, good controllability, and desirable scalability. The bulk morphologies of the synthesized CNTs can be sponge-like, an array, a thin film, or fiber by simply changing the growth parameters and the way they are collected, which facilitates a wide range of applications. The authors comprehensively review the state-of-the-art progress on the controlled growth of CNTs by FCCVD which have a defined number of walls, and controlled diameter, bundle size, and type of conductivity. The properties and possible applications for the CNTs and their hybrids are summarized. Finally, insights into the key challenges and prospects for CNTs synthesized by FCCVD are discussed.

“…The upward trend on the σ dc / σ oc value of SWNT TCFs with prolonged nitric acid treatment can be attributed to the increased functionalization of the SWNTs and the concomitant higher doping level. It is known from the literature that post‐treatment of SWNT films with HNO 3 improves the electrical conductivity through doping . Shin et al reported that TCFs fabricated from dispersion of SWNTs in N‐methylpyrrolidone solvent showed a significant decrease in R s from ca.…”

Single wall carbon nanotubes (SWNTs) are considered to be one of the potential candidates for the production of transparent conducting films (TCFs), which can be used in many applications, e.g., touch panels, displays, and polymer solar cells. However, for making optimum usage of the superior properties of SWNTs, a better understanding on the processing and fabrication of thin films is essential. In this work, the effects of the purification conditions of SWNTs, the stability of their dispersions as a function of pH, and the performance of TCFs fabricated from dispersions of different pH are studied. The figure of merit s dc /s oc for such films can be increased by factor of 2 when the pH of the SWNT dispersion is increased, i.e., the optical and electrical performance is improved significantly. We also report the surface charge-manipulated transformations in transparent conducting films fabricated from SWNT dispersions of different pH values.

“…Since the preparation method for CNT‐based TCFs using filtration‐transfer and dip‐coating techniques was first reported by Wu et al and Saran et al, respectively, in 2004, several leading research groups and companies have put considerable effort into this area. Until now, many solution‐processing methods such as vacuum filtration followed by transfer printing, dip coating, spin coating, spray coating, electrophoretic deposition (EPD), printing (rod coating, inkjet printing, and slot coating) and, recently, brush painting have been developed to fabricate CNT‐based TCFs. Of course all of these methods have advantages and disadvantages.…”

As one type of emerging photovoltaic cell, dye-sensitized solar cells (DSSCs) are an attractive potential source of renewable energy due to their eco-friendliness, ease of fabrication, and cost effectiveness. However, in DSSCs, the rarity and high cost of some electrode materials (transparent conducting oxide and platinum) and the inefficient performance caused by slow electron transport, poor light-harvesting efficiency, and significant charge recombination are critical issues. Recent research has shown that carbon nanotubes (CNTs) are promising candidates to overcome these issues due to their unique electrical, optical, chemical, physical, as well as catalytic properties. This article provides a comprehensive review of the research that has focused on the application of CNTs and their hybrids in transparent conducting electrodes (TCEs), in semiconducting layers, and in counter electrodes of DSSCs. At the end of this review, some important research directions for the future use of CNTs in DSSCs are also provided.
