Abstract

Dye is coabsorbed with CdSe nanocrystals, strongly increasing the amount of charge injected into TiO2 from CdSe nanocrystals and providing an additional degree of control over the electron charge-transfer process. This could have important implications in the development of supracollectors with enhanced absorption and chargeseparation properties for photovoltaic devices.
