Since the establishment of dye-sensitized solar cells in the early '90s, both the efficiency and stability of these third generation photovoltaics have been greatly enhanced. Nevertheless, there still exist many unwanted processes that impede operation of dye-sensitized solar cells, encumbering the achievement of the maximum theoretical power conversion efficiency and decreasing the devices' long-term operation. These processes include charge recombination, dye aggregation, dye desorption, and high protonation degrees of the semiconductor's surface. This Minireview focuses on a powerful strategy developed to address these problems, namely the use of co-adsorbents. All types of co-adsorbents utilized thus far are categorized in terms of the chemical identity of their anchoring group; in addition their operational mechanisms are presented and the properties that a functional molecule should possess to be applied as an efficient co-adsorbent are discussed.
自 90 年代初染料敏化太阳能电池问世以来，这类第三代光伏器件的效率和稳定性都得到了极大的提升。然而，仍然存在许多不理想的过程会阻碍染料敏化太阳能电池的运行，阻碍其达到最大理论功率转换效率，并降低器件的长期运行稳定性。这些过程包括电荷复合、染料聚集、染料解吸以及半导体表面的高质子化程度。本综述聚焦于一种用于解决这些问题的强大策略，即使用共吸附剂。迄今为止，所使用的各种共吸附剂都根据其锚定基团的化学性质进行了分类；此外，还介绍了它们的工作机制，并讨论了作为有效共吸附剂应用的功能分子应具备的性质。
