Chemical doping is an important strategy to alter the charge-transport properties of both molecular and polymeric organic semiconductors that find widespread application in organic electronic devices. We report on the use of a new class of Co(III) complexes as p-type dopants for triarylamine-based hole conductors such as spiro-MeOTAD and their application in solid-state dye-sensitized solar cells (ssDSCs). We show that the proposed compounds fulfill the requirements for this application and that the discussed strategy is promising for tuning the conductivity of spiro-MeOTAD in ssDSCs, without having to rely on the commonly employed photo-doping. By using a recently developed high molar extinction coefficient organic D-π-A sensitizer and p-doped spiro-MeOTAD as hole conductor, we achieved a record power conversion efficiency of 7.2%, measured under standard solar conditions (AM1.5G, 100 mW cm(-2)). We expect these promising new dopants to find widespread applications in organic electronics in general and photovoltaics in particular.

三（2-（1H-吡唑-1-基）吡啶）钴（III）作为有机半导体的p型掺杂剂及其在高效固态染料敏化太阳能电池中的应用

化学掺杂是改变分子和聚合物有机半导体电荷传输特性的重要策略，广泛应用于有机电子器件。我们报告了使用新型 Co(III) 配合物作为基于三芳胺的空穴导体（如螺-MeOTAD）的 p 型掺杂剂及其在固态染料敏化太阳能电池（ssDSC）中的应用。我们表明，所提出的化合物满足该应用的要求，并且所讨论的策略有望在 ssDSC 中调节螺-MeOTAD 的电导率，而不必依赖于常用的光掺杂。通过使用最近开发的高摩尔消光系数有机 D-π-A 敏化剂和 p 掺杂螺-MeOTAD 作为空穴导体，我们实现了创纪录的 7.2% 的功率转换效率，在标准太阳条件下测量 (AM1.5G, 100 mW cm(-2))。我们预计这些有前途的新型掺杂剂将广泛应用于有机电子领域，尤其是光伏领域。
