Photodetectors and photovoltaics based on semiconductor nanocrystals

摘要

A composite material is described. The composite material comprises semiconductor nanocrystals, and organic molecules that passivate the surfaces of the semiconductor nanocrystals. One or more properties of the organic molecules facilitate the transfer of charge between the semiconductor nanocrystals. A semiconductor material is described that comprises p-type semiconductor material including semiconductor nanocrystals. At least one property of the semiconductor material results in a mobility of electrons in the semiconductor material being greater than or equal to a mobility of holes. A semiconductor material is described that comprises n-type semiconductor material including semiconductor nanocrystals. At least one property of the semiconductor material results in a mobility of holes in the semiconductor material being greater than or equal to a mobility of electrons.

1. A composite material comprising:
semiconductor nanocrystals; and organic molecules to passivate the surfaces of the semiconductor nanocrystals, the organic molecules further to facilitate a transfer of charge between the semiconductor nanocrystals, the organic molecules further to crosslink a resultant composite material and thereby increase a volume density of the semiconductor nanocrystals within the resultant composite material and increase a stability of the resultant composite material in time.
