The incorporation of InP quantum-dot/N-doped multiwalled carbon nanotube (QD:NCNT) nanohybrids in the active layer of poly(3-hexylthiophene)/indene-C-60 bisadduct (P3HT/ICBA) bulk-heterojuction solar cells enhances V-OC and J(SC). The QDs encourage exciton dissociation by promoting electron transfer, while the NCNTs enhance the transport of the separated electrons and eventual charge collection. Such a synergistic effect successfully improves the power conversion efficiency (PCE) from 4.68% (reference cells) to 6.11%.
