Their potential toxicity in the biological environment has been debated over the past decade as the Cd 2+ ions released from the QD surface are highly toxic to the cells and tissues. [ 4 ] [ 5 ] Thus, many researchers have focused on the development of cadmium-free quantum dots ( CFQDs ) in the 2010s.
Carbon quantum dots also commonly called carbon nano dots or simply carbon dots (abbreviated as CQDs, C-dots or CDs) are carbon nanoparticles which are less than 10 nm in size and have some form of surface passivation. [1] [2] [3]

In a conventional solar cell light is absorbed by a semiconductor, producing an electron-hole (e-h) pair; the pair may be bound and is referred to as an exciton.This pair is separated by an internal electrochemical potential (present in p-n junctions or Schottky diodes) and the resulting flow of electrons and holes creates an electric current.
He has served on the boards of Boeing (1997-present), Dell (2011-present) and ConocoPhillips (2000-2012).
