摘要：

Indene addition product of [6,6]-phenyl-C-61-butyric acid methyl ester (PC60BM), indende PC60BM (IPC60BM), was synthesized by a one pot reaction of indene and PC60BM at 180 degrees C for 12 h, for combining the advantages of PC60BM and indene-C-60 bis-adduct In the application as acceptor in polymer solar cells (PSCs). The lowest unoccupied molecular orbital (LUMO) energy level of IPC60BM is 0.12 eV up-shifted than that of PC60BM The PSC based on poly(3-hexylthiophene) (P3HT) as donor and IPC60BM as acceptor shows a higher V-oc of 0.72 V and higher power conversion efficiency (PCE) of 4.39% under the illumination of AM1.5G, 100 mW/cm(2), while the PSC based on P3HT/PC60BM displays V-oc of 0.58 V and PCE of 3.49% only The results indicate that IPC60BM is a better acceptor than PC60BM for the P3HT-based PSCs and could be a promising new acceptor instead of PC60BM for high-performance PSCs.
