Abstract

Quantum Dots used in so-called third-generation Solar Cells have the potential to significantly increase the photon conversion efficiency in two ways: (1) the production of multiple excitons from a single photon of sufficient energy and (2) the formation of intermediate bands in the bandgap that enhances its photogenerated current, via the two-step absorption of sub-band gap photons.

 

Key words: Quantum Dot Solar Cells, Multiple Exciton Generation, Intermediate Band.
