Self-assembly and its impact on interfacial charge transfer in carbon nanotube/P3HT solar cells

ixtures of carbon nanomaterials and conjugated polymers have been used extensively as active materials in excitonic solar cells1 (XSC). Poly-3-hexylthiophene (P3HT) has proven thus far to be one of the best choices for the do-nor material in bulk heterojunction XSC,2 and its use in conjunction with single-walled carbon nanotubes (SWNTs)37 as the acceptor material is considered a natu-ral combination due to the very good hole and electron mobilities in the two materials, respectively, and the potentially ideal mor-phology of their distributed heterojunctionOprovided effective phas
