一种低带隙平面分子结构的聚合物合成
  • 摘要

    合成了一种给-受体型平面分子结构的低带隙共轭聚合物QP-1(聚[2,6-4,8-双十二烷氧基苯并[1,2-b;3,4-b']二噻吩-4,7-二[2,5-噻吩]-5,6-二烷氧基-2,1,3苯并噻二唑)),研究了其热学、光物理和光伏性质.由电化学测试得到聚合物的带隙为1.79eV,最高分子占有轨道HOMO和最低分子未占轨道LUMO值分别为-5.47 eV和-3.49 eV.与富勒烯的衍生物PCBM有较为理想的能级匹配水平.使用聚合物/PC71 BM共混物作为活性层构筑了本体异质结聚合物太阳能电池.光伏电池的能量转换效率为1.01%,开路电压为0.58 V,短路电流为4.25 mA/cm2,填充因子ff值为0.33.X射线粉末衍射(XRD)结果显示平面主链间的距离为0.365nm,具有较好的结晶性.
