A novel multifunctional conjugated polymer (RCP-1) composed of an electron-donating backbone (carbazole) and an electron-accepting side chain (cyanoacetic acid) connected through conjugated vinylene and terthiophene has been synthesized and tested as a photosensitizer in two major molecule-based solar cells, namely dye sensitized solar cells (DSSCs) and organic photovoltaic cells (OPVs). Promising initial results on overall power conversion efficiencies of 4.11% and 1.04% are obtained from the basic structure of DSSCs and OPVs based on RCP-1, respectively. The well-defined donor (D)-acceptor (A) structure of RCP-1 has made it possible, for the first time, to reach over 4% of power conversion efficiency in DSSCs with an organic polymer sensitizer and good operation stability.
一种新型多功能共轭聚合物（RCP-1）由电子给体主链（咔唑）和通过共轭亚乙烯基和三噻吩连接的电子受体侧链（氰基乙酸）组成，已被合成并用作两种主要基于分子的太阳能电池，即染料敏化太阳能电池（DSSC）和有机光伏电池（OPV）中的敏化剂。从基于 RCP-1 的 DSSC 和 OPV 的基本结构中，分别获得了令人鼓舞的 4.11%和 1.04%的整体功率转换效率的初始结果。RCP-1 的明确的给体（D）-受体（A）结构使其首次有可能在具有有机聚合物敏化剂和良好操作稳定性的 DSSC 中达到超过 4%的功率转换效率。
