Perovskite solar cells (PSCs) were first proposed in 2009. They have the advantages of low cost, a simple manufacturing process and excellent photoelectric performance. PSC electrodes are mainly made from precious metals such as gold and silver. Still, the cost of precious metals is high and they react with the other components of the PSCs, resulting in the poor stability of the photovoltaic device. Using carbon as an electrode material can both reduce the cost and significantly improve the stability of the photovoltaic device. However, the poor interface contact between the carbon electrode and perovskite and carbon electrode resistance results in poor photovoltaic device photoelectric performance. Finding a way to successfully utilize carbon as an alternative electrode material is a key step toward moving PSCs from the laboratory to industrialization. This paper reviews the application of carbon black, graphite, graphene, carbon nanotubes (CNTs) and composite carbon electrode in PSCs, focusing on progress in the research of doping, structure, interface modification and the production process.
钙钛矿太阳能电池(PSCs)于2009年首次被提出。它们具有成本低、制造工艺简单和光电性能优异的优点。PSC电极主要由金和银等贵金属制成。然而,贵金属成本高昂,且它们会与PSCs的其他组件发生反应,导致光伏器件稳定性较差。使用碳作为电极材料既能降低成本,又能显著提高光伏器件的稳定性。然而,碳电极与钙钛矿之间不良的界面接触以及碳电极电阻导致光伏器件的光电性能不佳。找到成功利用碳作为替代电极材料的方法是推动PSCs从实验室走向工业化的关键一步。本文综述了炭黑、石墨、石墨烯、碳纳米管(CNTs)和复合碳电极在PSCs中的应用,重点关注掺杂、结构、界面改性和生产工艺等方面的研究进展。
