QD/CNT hybrid nanomaterials enhance the exciton dissociation and electron transport in the bulk-heterojunction active layer of organic solar cells, as described by Sang Ouk Kim, Duk Young Jeon, and co-workers on page 2011. InP quantum dots (QDs) spontaneously bind at N-doped carbon nanotubes via electrostatic attraction. While the InP QDs encouraged the exciton dissociation, NCNTs enhanced the transport of the separated electrons. Such a synergistic effect successfully improved the PCE from 4.68% to 6.11%, which corresponds to 31% enhancement.
