英文摘要: Two new fullerene derivatives N3 and N6, derived from flourene, have been synthesized for the organic photovoltaic applications. The molecule N3 is a diarylmethano fullerene derivative, whereas N6 contains a chromophore 4-nitro-cyaostilbene (NCS). Their optical, electrochemical, and structural properties were systematically studied by H-1 and C-13 NMR, FT-IR, and UV-visible absorption spectroscopy. A series of bulk heterojunction polymer solar cells was constructed from these newly developed acceptors using PBDTTT-C-T and PTB7 as electron donors with different donor-to-acceptor weight ratios along with the variation in the volume percentage of DIO additive. The best solar cells made from PTB7:N3 and PTB7:N6 blends exhibited power conversion efficiencies of 4.1 and 3.6%, and the cells made from PBDTTT-C-T:N3 and PBDTTT-C-T:N6 blends exhibited power conversion efficiencies of 2.3 and 1.4%, respectively, with a very high open circuit voltage of over 0.85 V.
