Doping improves performance. N- or B-doped carbon nanotubes (CNTs) uniformly dispersed in the active layer of P3HT/PCMB (poly (3-hexylthiophene/[6,6]-phenyl-C61-butyric acid methyl ester) bulk-heterojunction solar cells selectively enhance electron or hole transport and eventually help carrier collection. Specifically, the incorporation of 1.0 wt% B-doped CNTs results in balanced electron and hole transport and accomplishes a power conversion efficiency improvement from 3.0% (without CNTs) to 4.1%.
掺杂可以提高性能。氮掺杂或硼掺杂的碳纳米管（CNTs）均匀分散在 P3HT/PCMB（聚（3-己基噻吩/[6,6]-苯基-C61-丁酸甲酯）体异质结太阳能电池的活性层中，可以选择性地增强电子或空穴传输，最终有助于载流子收集。具体来说，掺入 1.0wt%的硼掺杂 CNTs 可实现电子和空穴传输的平衡，并将功率转换效率从 3.0%（无 CNTs）提高到 4.1%。
