Solution-processed solar cells are appealing because of the low manufacturing cost, the good compatibility with flexible substrates, and the ease of large-scale fabrication. Whereas solution-processable active materials have been widely adopted for the fabrication of organic, dye-sensitized, and perovskite solar cells, vacuum-deposited transparent conducting oxides (TCOs) such as indium tin oxide, fluorine-doped tin oxide, and aluminum-doped tin oxide are still the most frequently used transparent electrodes (TEs) for solar cells. These TCOs not only significantly increase the manufacturing cost of the device, but also are too brittle for future flexible and wearable applications. Therefore, developing solution-processed TEs for solar cells is of great interest. This paper provides a detailed discussion on the recent development of solution-processed TEs, including the chemical synthesis of the electrode materials, the solution-based technologies for the electrode fabrication, the optical and electrical properties of the solution-processed TEs, and their applications on solar cells.
溶液处理的太阳能电池因其制造成本低、与柔性衬底兼容性好以及易于大规模制造而备受关注。虽然溶液可加工的活性材料已被广泛用于制造有机、染料敏化和钙钛矿太阳能电池，但真空沉积的透明导电氧化物（TCOs），如氧化铟锡、氟掺杂氧化锡和铝掺杂氧化锡，仍然是太阳能电池最常用的透明电极（TEs）。这些TCOs不仅显著增加了器件的制造成本，而且对于未来的柔性和可穿戴应用来说太脆了。因此，开发用于太阳能电池的溶液处理TEs引起了人们极大的兴趣。本文详细讨论了溶液处理TEs的最新进展，包括电极材料的化学合成、基于溶液的电极制造技术、溶液处理TEs的光学和电学性质及其在太阳能电池上的应用。
