The incorporation of InP quantum-dot/N-doped multiwalled carbon nanotube (QD:NCNT) nanohybrids in the active layer of poly(3-hexylthiophene)/indene-C60 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%.
将 InP 量子点/N 掺杂多壁碳纳米管（QD:NCNT）纳米杂化物掺入聚（3-己基噻吩）/茚并[2,1-b]噻吩-C60 双加成物（P3HT/ICBA）体异质结太阳能电池的活性层中，可提高开路电压（VOC）和短路电流密度（JSC）。量子点通过促进电子转移来促进激子解离，而 NCNTs 则增强了分离电子的传输以及最终的电荷收集。这种协同效应成功地将功率转换效率（PCE）从 4.68%（基准电池）提高到了 6.11%。
