CdSe Nanowire/Fullerene Nanocomposite Photoelectrode: Charge Separation and Photoelectrochemical Behavior

The fabrication of semiconductor nanocomposites with a staggered band-edge alignment has been widely adapted to facilitate charge separation, thus harnessing more photons in light-harvesting systems.1 To date, a variety of semiconductor nanocomposites have been developed ranging from purely inorganic nanocomposites to organic/inorganic hybrid ana-logues.2-7 Among the organic/inorganic hybrid nanocom-posites, semiconductor/fullerene (C60) based nanohetero-structures have been widely investigated due to the excellent electron-accepting ability of C60. 8-14 While a wide variety of QD/C60 hybrid nanocomposites have been reported, no attempt has been made toward combining semiconductor nanowires (NWs) with C60 to date. In comparison to QDs, semiconductor NWs can be potentially advantageous i
