Abstract

All photosynthetic organisms contain light-harvesting antenna complexes and electron transfer complexes called reaction centers. Some photosynthetic bacteria contain large (∼100 MDa) peripheral antenna complexes known as chlorosomes. Chlorosomes lose their reaction center when they are extracted from organisms. Lead sulfide (PbS) quantum dots (QDs) were used for artificial reaction centers. Successive ionic layer adsorption and reaction (SILAR) allows different sizes of PbS QDs with different cycles to be easily deposited onto the nanostructured columnar titanium dioxide (TiO2) film with single crystal. Chlorosomes were sequentially deposited onto the PbS QDs surface by electrospray. Compared to the typical PbS QD sensitized solar cells, overall energy conversion efficiency increased with the Förster resonance energy transfer (FRET) effect between PbS QDs and chlorosomes.
