and multianchoring asymmetric tribranched organic photosensitizer (i.e., TB-PT) for dye-sensitized solar cells containing three different (D–π–D, D–π1–A, and D–π2–A; D = electron-rich moiety, A = electron-poor moiety, π = conjugated bridge) polar branches, two donor cores, and two acceptor/anchoring groups to TiO2 was investigated and compared with the corresponding symmetric dyes. TB-PT combines the
一种用于染料敏化太阳能电池的新型多供体和多锚定不对称三分支有机光敏剂(即 TB-PT),包含三种不同的(D–π–D、D–π1–A 和 D–π2–A;D = 富电子部分,A = 缺电子部分,π = 共轭桥)极性分支,两个供体核和两个受体/锚定基团到 TiO2 进行了研究,并与相应的对称染料进行了比较。TB-PT 结合了其 π 扩展三支化结构和分子内共敏化方法所产生的优势,从而增强了定制的光学和能量特性,并最终提高了光伏性能。
