polypyridyl redox shuttles were synthesized in the 2+ and 3+ oxidation states and paired with a series of wide optical gap organic dyes with weak aryl ether electron-donating groups. High voltage dye-sensitizedsolarcell (HV-DSC) devices were obtained through controlling the redox shuttle energetics and dye donor structure. The use of aryl ether donor groups, in place of commonly used aryl amines, allowed
合成了一系列具有 2+ 和 3+ 氧化态的铁聚吡啶基氧化还原梭,并与一系列具有弱芳醚给电子基团的宽光隙有机染料配对。通过控制氧化还原穿梭能量和染料供体结构获得高压染料敏化太阳能电池(HV-DSC)器件。使用芳醚供体基团代替常用的芳胺,可以降低染料基态氧化电位,这使得基于 Fe 2+ 多吡啶基结构的氧化还原梭的氧化变得具有挑战性,以用于功能器件。通过仔细设计的染料系列是改变烷基链的数目为二氧化钛2表面的保护,电子以TiO重组2 氧化的氧化还原穿梭可以被控制,导致高达 1.4 V 的 HV-DSC 设备。

Energy conversion: A cobalt redox mediator, [Co(bpyPY4)]2+/3+, based on a hexadentate polypyridyl ligand, was developed. Dye‐sensitizedsolarcells (DSCs) made with this redox mediator showed improved stability and slightly higher efficiencies compared to [Co(bpy)3]2+/3+‐based devices. Long‐term stability evaluation of DSCs based on [Co(bpyPY4)]2+/3+ revealed excellent stability under full irradiation
