| 英文摘要 | an alternating polymer (pfoftqx) with 9,9-dioctylfluorene (fo) as electron-rich unit and fluorine substituted quinoxaline (ftqx) as electron-withdrawing unit was synthesized and characterized. pfoftqx showed similar absorption property with that of the counterpart polymer without fluorine atom (synthesized apfo-15). however, the low-lying highest occupied molecular orbit (homo) energy level of pfoftqx was -5.37 ev, about 0.07 ev smaller than that of synthesized apfo-15. in order to study the photovoltaic properties of the materials, polymer solar cells (pscs) were fabricated with pfoftqx as donor blended with [6,6]-phenyl-c61-butyric acid methyl ester (pc61bm) as acceptor. the power conversion efficiency (pce) of psc was 1.77% with a high open-circuit voltage (v-oc) of 0.90 v for an optimized pfoftqx:pc61bm weight ratio of 1:5, in comparison with that of synthesized apfo-15-based device (pce of 1.60% with v-oc of 0.77 v). this study indicated that fluorine substituted quinoxaline-based polymers would be promising material with a higher v-oc for the application in polymer solar cells.
