Hybrid halide perovskite solar cells were first demonstrated in 2009 with cell efficiency quickly soaring from below 10% to more than 23% in a few years. Halide perovskites have the desirable processing simplicity but are very fragile when exposed to water and heat. This fragility represents a great challenge for the achievement of their full practical potential in photovoltaic technologies. To address this problem, here we review the recent development of the mixed-dimensional perovskites, whereby the trade-off between power conversion efficiency and stability of the material can be finely tuned using organic amine cations with different sizes and functionalities.
混合卤化物钙钛矿太阳能电池于 2009 年首次被证明，其电池效率在短短几年内迅速从低于 10%飙升至超过 23%。卤化物钙钛矿具有理想的加工简单性，但暴露在水和热中时非常脆弱。这种脆弱性对实现其在光伏技术中的全部实际潜力构成了巨大挑战。为了解决这个问题，我们在这里回顾了混合维钙钛矿的最新发展，通过使用具有不同大小和功能的有机胺阳离子，可以精细地调整材料的功率转换效率和稳定性之间的权衡。
