Carbon Nanotube: Synthesis and Application in Solar Cell

Abstract

Carbon nanotubes and fullerenes have a cylindrical and hollow spherical molecular structure with outstanding mechanical and electronic properties. Their versatility is outstanding and envisioned by the wide application range from field emission displays to impregnated metal composites, battery storage media, and nano-electronic devices. The combination of simple materials, diverse behavior, and ease of fabrication make these materials a cornerstone topic in current research. They have very wide applications in electronic devices and identifying the potential applications which is due to low bias transport at several nanometers. Since valance and conduction bands are symmetric, so they have a direct band gap and due to this it can be used in optical emission. CNTs can be synthesized via three techniques such as arc discharge, laser ablation and chemical vapor deposition, but the CVD process is mainly used for the synthesis because the CNT yield in such case will be more than 98 % pure. 100 % pure MWCNTs having multiple chirality results the enhanced optical property and better employment as light harvesting material. The dye sensitized solar cells are fabricated using CNT composites and functionalized nanotubes. The synthesis of CNT and its application in solar cell are presented in this short review.
