Carbon Nanotube-Polymer Nanocomposite for Organic Solar Cell Applications

The widespread adoption of renewable energy technologies depends on the development of organic solar cells (OSCs) that are both efficient and affordable. Because of their remarkable electrical, optical, and mechanical qualities, carbon nanotubes (CNTs) have become attractive options for improving the functionality of organic solar cells (OSCs). The creation and characterization of a CNT-polymer nanocomposite material for OSC applications are the subjects of this study. The charge transport and light-harvesting properties of the nanocomposite material were greatly enhanced by the addition of CNTs. When using the CNT-polymer nanocomposite as the active layer, OSC devices exhibit a substantial improvement in power conversion efficiency compared to the original polymer-based devices. The enhanced functionality is ascribed to the effective separation and transportation of charges enabled by the permeating web of carbon nanotubes inside the polymer matrix. In this chapter, we have discussed the role of CNTs as an active layer in OSCs, the effect of CNTs on organic photovoltaic parameters, and future applications.
