Abstract

Two novel conjugated polymers comprised of 2,3-R₂-di- thieno[3,2-f:2’,3’-h]quinoxaline, where R is 3’-(octyloxy)- phenyl (P1) or 2’-(2-ethylhexyl)thiophen-4’-yl (P2), and 2,1,3-benzothiadiazole have been synthesized using the Stille cross-coupling reaction. The synthesized polymers were investigated as hole transport layer (HTL) materials in perovskite solar cells. Polymer P2 as an HTL material provided improved short-circuit current and open-circuit voltage and, correspondingly, enhanced power conversion efficiency of perovskite solar cells compared to that of polymer P1.

作为过氧化物太阳能电池空穴传输材料的新型二噻吩并[3,2-f:2',3'-h]喹喔啉基聚合物

利用 Stille 交叉偶联反应合成了由 2,3-R2-二噻吩并[3,2-f:2',3'-h]喹喔啉（其中 R 为 3'-(octyloxy)- phenyl (P1)或 2'-(2-ethylhexyl)thiophen-4'-yl (P2)）和 2,1,3-苯并噻二唑组成的两种新型共轭聚合物。研究人员将合成的聚合物用作过氧化物太阳能电池中的空穴传输层（HTL）材料。与聚合物 P1 相比，作为 HTL 材料的聚合物 P2 可提供更好的短路电流和开路电压，并相应地提高过氧化物太阳能电池的功率转换效率。

期刊介绍： Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications. Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
