Power conversion efficiency (PCE) values of photovoltaic devices fabricated using these conjugated polymers were strongly related to the light absorbance and crystallinity in a film of the blend of polymer and [6,6]-phenyl C71-butyric acid methyl ester (PC71BM).

    In this work, a new electron-rich building block, o-fluoro-p-alkoxyphenyl-substituted benzo[1,2-b:4,5-b′]dithiophene (BDT) unit, has been used to construct donor (D)–acceptor (A) conjugated copolymers with electron-deficient units 5,6-difluoro-4,7-di(4-(2-ethylhexyl)-2-thienyl)-2,1,3-benzothiadiazole (C8DTBTff) and 5,6-difluoro-4,7-di(4-hexyl-2-thienyl)-2,1,3-benzothiadiazole (C6DTBTff), named P-o-FBDTP-C8DTBTff

    molecules in the active layer have a crucial influence on photovoltaic properties of organic solar cells. In this work, we design an A1-(D-A)2-D-A1 type oligomer DRCN4FBT on the basis of an A1-D-A-D-A1 type small molecule DRCN2FBT by inserting D-A unit. It is found that oligomer DRCN4FBT exhibits wider absorption spectrum and higher carrier mobility and better morphology than small molecule DRCN2FBT
    活性层中分子的吸收,迁移率和形态对有机太阳能电池的光伏性能具有至关重要的影响。在这项工作中,我们通过插入DA单元,在A 1 -DADA 1型小分子DRCN2FBT的基础上设计A 1-(DA)2 -DA 1型低聚物DRCN4FBT 。发现在使用富勒烯PC 71的活性层中,低聚物DRCN4FBT表现出比小分子DRCN2FBT宽的吸收光谱和更高的载流子迁移率以及更好的形态。BM为受体。通过在DRCN2FBT中插入DA单元,可以很好地监控活性层中DRCN4FBT的吸收,能级,迁移率和形态。结果,与基于DRCN2FBT / PC 71 BM的器件相比,基于DRCN4FBT / PC 71 BM的有机太阳能电池的功率转换效率和短路电流密度提高了约20%。这表明简单地增加小分子中的DA单元以构建低聚物是改善光伏性质的有效策略。
  • Two-Dimensionally Extended π-Conjugation of Donor–Acceptor Copolymers via Oligothienyl Side Chains for Efficient Polymer Solar Cells
    作者:Jaewon Lee、Joo-Hyun Kim、Byungho Moon、Heung Gyu Kim、Min Kim、Jisoo Shin、Hyeongjin Hwang、Kilwon Cho

    A series of two-dimensional conjugated polymers containing p-conjugated oligothienyl side chains, namely PBDT2FBT-T1, PBDT2FBT-T2, PBDT2FBT-T3, and PBDT2FBT-T4, was designed and synthesized to investigate the effect of two-dimensionally extended pi-conjugation on the polymer solar cell (PSC) performance. The oligothienyl units introduced into the side chains significantly affect the optoelectronic properties of the parent polymers as well as the performances of the resulting solar cell devices by altering the molecular arrangement and packing, crystalline behavior, and microstructure of the polymer:PC71BM blend films. The crystallinity and blend morphology of the polymers can be systematically controlled by tuning the pi-conjugation length of side chains; PBDT2FBT-T3 exhibited the most extended UV/vis light absorption band and the highest charge mobility, leading to a high short-circuit current density up to 12.5 mA cm(-2) in the relevant PSCs. The PBDT2FBT-T3:PC71BM-based PSC exhibited the best power conversion efficiency of 6.48% among this series of polymers prepared without the use of processing additives or post-treatments. These results provide a new possibility and valuable insight into the development of efficient medium-bandgap polymers for use in organic solar cells.
  • Fluorinated Benzothiadiazole-Based Conjugated Polymers for High-Performance Polymer Solar Cells without Any Processing Additives or Post-treatments

    Thanks to their many favorable advantages, polymer solar cells exhibit great potential for next-generation clean energy sources. Herein, we have successfully designed and synthesized a series of new fluorinated benzothiadiazole-based conjugated copolymers PBDTTEH-DT(H)BTff (P1), PBDTTEH-DT(EH)BTff (P2), and PBDTHDO-DT(H)BTff (P3). The power conversion efficiencies of 4.46, 6.20, and 8.30% were achieved for P1-, P2-, and P3-based devices within similar to 100 nm thickness active layers under AM 1.5G illumination without any processing additives or post-treatments, respectively. The PCE of 8.30% for P3 is the highest value for the reported traditional single-junction polymer solar cells via a simple fabrication architecture without any additives or post-treatments. In addition, it is noteworthy that P3 also allows making high efficient polymer solar cells with high PCEs of 7.27 and 6.56% under the same condition for similar to 200 and similar to 300 nm thickness active layers, respectively. Excellent photoelectric properties and good solubility make polymer P3 become an alternative material for high-performance polymer solar cells.
