Application of Carbonaceous Quantum Dots in Solar Cells

Carbonaceous Quantum Dots (CQDs) are gaining the interest of various research groups owing to their significant features, including water stability, biocompatibility, minimal cytotoxicity, chemical inertness and fluorescence which make them a good candidate in solar cells applications such as photocatalysis, solar energy conversion, photovoltaic solar cells, and Photoelectrochemical cells. CQDs are used in photocatalytic reactions because they can be used as electron sinks to stop the coupling of electron void pairs. The high coefficient of absorption and the broad spectrum of absorption improve the photocatalytic activity. In solar cells, the CQDs are used as sensitizers. CQDs are employed in solar energy generation because they are non-toxic and affordable. This chapter discusses the use of CQDs in solar cells.
