A Review on Applications of Carbon Nanotubes (CNTs) in Solar Cells

The world is looking for clean, renewable and cheap energy. For a long time, researchers have been trying to find materials to achieve this goal. The discovery of carbon nanotubes (CNTs) has opened new horizons in the field of their uses in the field of solar energy. The chemistry of carbon nanotubes involves chemical reactions that are used to change the properties of carbon nanotubes (CNTs). To attain desired properties that can be used in a wide range of applications, CNTs can be functionalized. Covalent and non-covalent modifications are the two primary types of CNT functionalization. This review focuses on how to use the synthesized CNTs by flame fragments deposition (FFD) technique, which is an easy and cheap method in which CNTs can be prepared at lower temperatures compared with other traditional techniques, in preparing CNTs composites in solar cell components to improve charge conduction, electrode flexibility and acting as active light absorbing materials.
