| 英文摘要 | A new two-dimensional (2d) conjugated small molecule, namely dca3tbdtp, with an alkoxyphenyl substituted benzo[1,2-b: 4,5-b']dithiophene (bdt) unit as the central core, octyl cyanoacetate as the end-capped groups and terthiophene as the pi-linked bridge, was designed and synthesized for solution-processed organic solar cells (oscs) as an electron donor material, in which an alkoxyphenyl group was introduced as a weak electrondonating side chain of the bdt moiety. the dca3tbdtp molecule exhibited good solubility, a deep highest occupied molecular orbital (homo) level (-5.25 ev), an appropriate optical band-gap (1.82 ev) and a high decomposition temperature (362 degrees c). by applying the simple solution spin-coating fabrication process, the bulk heterojunction (bhj) oscs based on dca3tbdtp and [6,6]-phenyl-c-61-butyric acid methyl ester (pc61bm) exhibited a good power conversion efficiency (pce) of 4.51% with a high open-circuit voltage (v-oc) of 0.90 v when thermal annealing at only 70 degrees c. |
