Abstract
Electrically conducting thin-film materials possessing high transparency are essential components for many optoelectronic devices. The advancement in the transparent conductor applications requires a replacement of indium tin oxide (ITO), one of the key materials in electronics. Despite being the most commonly used transparent conductive material, ITO as well as other metal oxides have several drawbacks, including limited mechanical flexibility, high refractive index and haze, limited chemical stability, and depleted raw material supply. Single-walled carbon nanotubes (SWCNTs) are one of the most promising alternative material platforms considered for transparent conducting films (TCFs) due to their excellent optoelectronic properties and unique mechanical flexibility and stretchability. Here, we analyze the latest achievements in the optoelectronic performance of TCFs based on SWCNTs. We also describe the roadmap for further research and development of the transparent conductors employing “rational design”, which breaks the deadlock for the TCFs obtained close to the theoretically limited performance.
