Dye is coabsorbed with CdSe nanocrystals (see image), strongly increasing the amount of charge injected into TiO 2 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 charge‐separation properties for photovoltaic devices.
