Nanocomposites comprising well‐mixed semiconductor nanocrystals and conjugated polymers that have relative offset energy band structures can not only complement the light absorption range of the solar spectrum but also result in a dissociation of charge‐transferred excitons upon absorption, with electrons transferring to the nanocrystals and holes remaining in the conjugated polymers. On page 4427, K.‐H. Wei and co‐workers find that this generates a photocurrent for photovoltaic applications or for reducing/oxidizing reactions for photocatalysis applications.
