Chirality Engineering of Carbon Nanotubes, Modeling and Photons Density Improvement for Solar cell Applications

Abstract

Carbon nanotubes and fullerenes offer exceptional mechanical and electrical qualities due to their cylindrical and hollow spherical molecular structures. Their extensive range of applications, which includes field emission displays, impregnated metal composites, battery storage media, and nanoelectronics devices, demonstrates their exceptional adaptability. The combination of simple materials, variable behavior, and simplicity of manufacture makes these materials a focal point of contemporary research. Due to the low bias transmission at a few nanometers, they have a wide range of applications in electronic devices, and finding their potential applications is a complicated process. Due to the fact that the valance and conduction bands are symmetric, they have a straight band gap and can be exploited for optical emission. Three processes, including arc discharge, laser ablation, and chemical vapor deposition, can be used to generate carbon nanotubes (CNTs), although chemical vapor deposition (CVD) is the most used method since it yields CNTs that are more than 98% pure. Multiple chirality of 100% pure MWCNTs results in enhanced optical properties and improved use as a light harvesting material. Using CNT composites and functionalized nanotubes, the dye-sensitized solar cells are constructed. In this brief review, the synthesis of CNT and its application in solar cells are discussed.
