摘要:

近年来, 有机-无机杂化钙钛矿太阳能电池以其优异的性能和低廉的制造成本受到了广泛关注。然而, 其含有铅元素的毒性以及稳定性阻碍了进一步商业化应用。双钙钛矿材料Cs2AgBiBr6具有稳定性优异、毒性低、载流子寿命长和载流子有效质量小的优势, 是一种颇具潜力的光伏材料, 已被应用于太阳能电池并展现出良好的性能。但是Cs2AgBiBr6钙钛矿太阳能电池的光电转换效率还无法与有机-无机杂化钙钛矿太阳能电池相媲美, 发展仍面临诸多挑战。本文首先介绍了Cs2AgBiBr6的晶体结构及容忍因子等结构参数; 然后介绍了溶液法、反溶剂辅助成膜法、气相法、真空辅助成膜法以及喷涂法等薄膜制备工艺的进展, 评述了各种薄膜制备工艺的优缺点; 接着从元素掺杂、添加剂工程及界面工程(界面能级匹配和界面缺陷钝化)三方面介绍了Cs2AgBiBr6钙钛矿太阳能电池的性能优化策略, 结合近年来的研究进展进行了评述; 最后指出Cs2AgBiBr6钙钛矿太阳能电池面临的挑战, 并从前驱体溶剂工程、带隙工程以及器件降解机理三方面展望了未来研究方向。

Abstract:

In recent years, organic-inorganic hybrid perovskite solar cells have received a lot of attention for their excellent performance and low manufacturing cost. However, the toxicity of lead in organic-inorganic hybrid perovskite solar cells and instability inhibits its further commercialization. Double perovskite Cs2AgBiBr6 possess excellent stability, low toxicity, long carrier lifetime, and small effective carrier mass, and is considered as a promising photovoltaic material. It has been applied in solar cells and displayed superior performance. However, the power conversion efficiency of Cs2AgBiBr6 perovskite solar cell still lags behind organic-inorganic hybrid perovskite solar cells, and its development faces various challenges. This review firstly introduces the crystal structure and the structural parameters such as tolerance factor of Cs2AgBiBr6. And then, the progress of thin film preparation technologies such as solution processing method, anti-solvent assisted film forming method, vapor deposition processing method, vacuum-assisted film forming method, spray-coating method are summarized, and the advantages and disadvantages of various preparation technologies are discussed. The performance optimization strategies of Cs2AgBiBr6 perovskite solar cells are analyzed from three aspects: element doping, additive engineering, and interface engineering (interface energy level matching and interface defect passivation), and the research progress in recent years is reviewed. Finally, the challenges faced by Cs2AgBiBr6 perovskite solar cells are pointed out, and future research directions are prospected from three aspects: precursor solvent engineering, bandgap engineering, and device degradation mechanism.
