摘要

摘要: 以芝麻油为原料，采用化学气相沉积法合成出多壁碳纳米管（MWCNTs），经功能化改性、切短后用作有机光伏太阳能电池的添加剂。该有机光伏电池以聚3-辛基噻吩为光敏分子，PCBM为激子离化剂。结果表明，添加MWCNTs与功能化且切短的fc-MWCNTs，有机光伏电池的功率转换效率能分别提高22%和40%。由于较高的空穴迁移率，激子离化后，P3OT产生空穴的收集和运输得到提高。功能化和切短的fc-MWCNTs增加了其在P3OT，PCBM中的分散性，进而提高功率转换效率。

Abstract: MWCNTs were synthesized by chemical vapor deposition from Sesamum indicum oil, functionalized, cut into short lengths and used as additives in organic photovoltaic solar cells (OPVs) using poly (3-octylthiophene) (P3OT) as a photoactive molecule and (6,6)-phenyl-C61-butyric acid methyl ester (PCBM) as an exciton dissociation agent. Results indicate that the addition of the MWCNTs and the functionalized and cut MWCNTs increases the power conversion efficiency of the OPVs by 22% and 40%, respectively. MWCNTs improve the collection and transportation of holes from the P3OT after exciton dissociation owing to their high hole mobility. The functionalization and cutting of MWCNTs improves their dispersion in P3OT and PCBM, which further increases the power conversion efficiency.
