Abstract
As one of the most attracting nanoscale materials in the past decade, graphene and composites based on graphene have boosted the efficiency of catalytic reaction in energy conversion applications. Charge collection and transport are facilitated with the presence of graphene and reduced graphene oxide in quantum dot solar cells. The 2-D graphene and its derivatives serve as a scaffold for the immobilization of catalytic and photovoltaic nanoparticles as well as promoting selectivity and efficiency of the reaction process. Small size graphene quantum dots, which have quantum confinement effect, are promising for the applications in photovoltaic devices, due to their outstanding properties and advantages, including high optical absorption, tunable bandgap, and earth abundant chemical composition. In this chapter, the synthesis and application of both graphene sheets and graphene quantum dots are highlighted, followed by a perspective of future research in this area.
