PHOTOACTIVE MATERIALS CONTAINING GROUP IV NANOSTRUCTURES AND OPTOELECTRONIC DEVICES MADE THEREFROM

摘要

The present invention provides photoactive materials that include inorganic nanostructures comprising a Group IV semiconductor in combination with electron transporting conjugated small molecules, carbon nanostructures or both. The carbon nanostructures or conjugated small molecules may be selected such that the inorganic nanostructures and the carbon nanostructures (and/or the small molecules) exhibit a type II band offset. The photovoltaic materials are well-suited for use as the active layer in photoactive devices, including photovoltaic devices, photoconductors and photodetectors.
