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.

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.
A widespread practical application is using quantum dot enhancement film (QDEF) layer to improve the LED backlighting in LCD TVs.Light from a blue LED backlight is converted by QDs to relatively pure red and green, so that this combination of blue, green and red light incurs less blue-green crosstalk and light absorption in the color filters after the LCD screen, thereby increasing useful ...
