Definition Of Exciton: An exciton is a bound state of an electron and hole which are attracted to each other by the electrostatic Coulomb force. It is an electrically neutral quasiparticle that exists in insulators, semiconductors and some liquids. The exciton is regarded as an elementary excitation of condensed matter that can transport energy without [...]

Multiple exciton generation (MEG), or carrier multiplication, involves the generation of multiple electron-hole pairs from the absorption of a single photon. MEG may considerably increase the power conversion efficiency of nanocrystal based solar cells, though harvesting the energy may be difficult because of the short lifetimes of the multiexcitons. More Info: Multiple Exciton Generation in [...]
