Organic solar cells (OSCs) are a promising low-cost thin-film photovoltaic technology while the fabrication of transparent conductive oxide (TCO) and metal electrodes still remains a factor that hinders the scaling-up and commercialization of OSCs. Carbon-based materials are regarded as potential alternatives due to their excellent properties, such as low cost, solution processibility, high conductance, and good chemical stability. In this mini-review, the recent progress of carbon-based materials such as graphite, carbon nanosheets, graphene, and carbon nanotubes to replace the TCO and metal electrodes of OSCs is surveyed. The preparation methods of different carbon-based materials are also discussed. Based on current progress, we summarize the outlooks and challenges of carbon-based electrodes. We anticipate this mini-review will inspire more research efforts to develop high-performance and OSC-matched carbon materials for more efficient and stable carbon-electrode-based OSCs.
有机太阳能电池 (OSCs) 是一种很有前途的低成本薄膜光伏技术，而透明导电氧化物 (TCO) 和金属电极的制造仍然是阻碍 OSCs 规模化和商业化的一个因素。基于其优异的性能，如低成本、溶液加工性、高导电性和良好的化学稳定性，碳基材料被认为是潜在的替代品。在这个小型综述中，调查了石墨、碳纳米片、石墨烯和碳纳米管等碳基材料替代 OSCs 的 TCO 和金属电极的最新进展。还讨论了不同碳基材料的制备方法。基于当前的进展，我们总结了碳基电极的展望和挑战。我们期望本小型综述将激发更多的研究努力，开发出高性能和与 OSC 匹配的碳材料，以实现更高效和稳定的基于碳电极的 OSCs。
