| 英文摘要 | A solution processible organic conjugated molecule 2-[2,6-bis-(2-{4-[2-(4-diphenylaminophenyl)vinyl]phenyl}vinyl)pyran-4-ylidene]malononitrile (tpa-dcm-tpa) was designed and synthesized for application in organic solar cells (oscs). the molecule consists of two electron-rich triphenylamine moieties and one electron-deficient 2-pyran-4-ylidenemalononitrile unit linked with conjugated bridges. the optical and electrochemical properties, the light-induced electron spin resonance (lesr), and the electronic ground state configuration of the compound were characterized. tpa-dcm-tpa film showed a broad absorption band covering from 350 to 650 nm. the bulk-heterojunction oscs with the device structure of ito/pedot:pss/tpa-dcm-tpa:pcbm/lif/al or ba/al were fabricated, in which tpa-dcm-tpa was used as donor and pcbm as acceptor material. the open-circuit voltage, short-circuit current, and power-conversion efficiency of the optimized osc with ba/al as cathode, tpa-dcm-tpa:pcbm = 1:3 (w/w), and ca. 85 nm thickness of the active layer reached 0.9 v, 2.14 ma/cm(2), and 0.79%, respectively, under the illumination of am1.5, 100 mw/cm(2). the results indicate that tpa-dcm-tpa is a promising photovoltaic organic molecule. |
