Abstract

Novel two-dimensional conjugated copolymer, abbreviated as PDTBSeVTT-2TF, containing electron-deficient 4,7-di(thiophen-2-yl)benzo[][1,2,5]selenodiazole (DTBSe) unit, conjugated vinyl-terthiophene (VTT) side chain and 3,3'-difluoro-2,2'-bithiophene (2TF) was designed and synthesized using microwave-assisted Stille cross-coupling polymerization. UV⁻visible absorption and cyclic voltammetry studies revealed that this copolymer possesses a strong and broad absorption in the range of 300⁻800 nm and a narrow optical bandgap () of 1.57 eV with low-lying HOMO and LUMO energy levels. Further, the bulk heterojunction polymer solar cells (PSCs) were fabricated using PDTBSeVTT-2TF as donor and [6,6]-phenyl-C-butyric acid methyl ester (PCBM) as acceptor with an inverted device structure of ITO/ZnO/PDTBSeVTT-2TF:PCBM/V₂O₅/Ag. The processing temperature of blend solution for preparing PDTBSeVTT-2TF:PCBM active layer showed obvious impact on the photovoltaic performance of solar devices. The cell fabricated from the blend solution at 65 °C exhibited enhanced power conversion efficiencies (PCE) of 5.11% with a of 10.99 mA/cm compared with the one at 50 °C, which had a PCE of 4.69% with a of 10.10 mA/cm. This enhancement is due to the dissolution of PDTBSeVTT-2TF clusters into single molecules and small aggregates, improving the miscibility between the polymer and PCBM and thus increasing the donor/acceptor interface.

摘要

设计并合成了一种新型二维共轭共聚物，简称为PDTBSeVTT-2TF，它含有缺电子的4,7-二(噻吩-2-基)苯并[][1,2,5]硒二唑(DTBSe)单元、共轭乙烯基-对三联噻吩(VTT)侧链和3,3'-二氟-2,2'-联噻吩(2TF)，采用微波辅助的Stille交叉偶联聚合反应制备。紫外可见吸收和循环伏安研究表明，该共聚物在300-800nm范围内具有强烈而宽泛的吸收，光学带隙()窄，为1.57eV，HOMO和LUMO能级较低。此外，以PDTBSeVTT-2TF为给体、[6,6]-苯基-C-丁酸甲酯(PCBM)为受体制作了本体异质结聚合物太阳能电池(PSC)，器件结构为ITO/ZnO/PDTBSeVTT-2TF:PCBM/V₂O₅/Ag。制备PDTBSeVTT-2TF:PCBM活性层的共混溶液的加工温度对太阳能器件的光伏性能有明显影响。与在50℃下制备的电池相比，在65℃下由共混溶液制备的电池的功率转换效率(PCE)提高到5.11%，电流密度为10.99mA/cm²，而在50℃下制备的电池的PCE为4.69%，电流密度为10.10mA/cm²。这种提高是由于PDTBSeVTT-2TF聚集体溶解为单分子和小聚集体，改善了聚合物与PCBM之间的混溶性，从而增加了供体/受体界面。
