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.
