| 摘 要： | 以吡咯并[3,4-c]吡咯二酮(DPP)为A单元,苯并[1,2-b∶4,5-b′]二噻吩(BDT)和萘为D单元,合成了一种新型2D/A型三元共轭聚合物太阳能电池给体材料(PDPP-BDT-NT),通过核磁共振氢谱(1 H NMR)对其结构进行了表征,通过热重分析、紫外-可见吸收光谱(UV-Vis)、循环伏安法对其热学性质、光物理性能及能级结构进行了研究。PDPP-BDT-NT具有较好的热稳定性,热分解的温度为401℃,有较宽的吸收光谱,可覆盖300~900nm,最高占据轨道(HOMO)能级为-5.35eV。以聚合物PDPP-BDT-NT为给体材料,PC60BM为受体材料,制备了一系列有机聚合物太阳能电池,在大气质量(AM)为1.5G,功率为100mW·cm-2模拟的太阳光照射下,有机聚合物太阳能电池的光电转化效率(PCE)可达2.09%。甲醇处理后,有机聚合物太阳能电池的PCE可达2.34%。

| Abstract: | A new random 2D/A terpolymer PDPP-BDT-NT comprising diketopyrrolo[3,4-c]pyrrole-1,4-dione (DPP) as A unit,benzo[1,2-b ∶ 4,5-b']dithiophene (BDT) and naphthalene (NT) as D units has been designed and synthesized via Stille coupling polymerization specifically for polymer solar cells (PSCs).Its structure was defined by proton nuclear magnetic resonance (1H NMR).And its thermogravimetric analysis,photophysical properties and energy-level structure were studied by thermal property,ultraviolet-visble (UV-Vis) absorption spectra,and cyclic voltammetry(CV).PDPP-BDT-NT exhibited good thermal stability with a decomposition temperature over 401 ℃.The terpolymer presented both broad absorption (300-900 nm) and low highest occupied molecular orbital level for-5.35 eV.Preliminary studies of bulk heterojunction (BHJ) solar cells based on PDPP-BDT-NT as donor material with PC60 BM as acceptor material showed a promising power conversion efficiency (PCE) of 2.09 ％ without any processing and post-treatment (under the illumination of AM 1.5,100 mW · cm-2),after MeOH treatment,the PCE of polymer solar cell was raised to 2.34％. |
