Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>The incorporation of InP quantum‐dot/N‐doped multiwalled carbon nanotube (QD:NCNT) nanohybrids</bold> in the active layer of poly(3‐hexylthiophene)/indene−C₆₀ bisadduct (P3HT/ICBA) bulk‐heterojuction solar cells enhances <italic>V</italic>_OC and <italic>J</italic>_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%. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg1x46ntrn" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
