Abstract

Highlights

The lanthanide compound of TbCl₃ improved the wettability of Me-4PACz and further enhanced crystallization, in which the additional Cl⁻ ions passivate iodine vacancy and improve energy level alignment at buried interface.
The inverted CsPbI₃ PSCs with TbCl₃ achieved a remarkable efficiency of 18.68% and enhanced stability in ambient air.
Efficiencies of 29.40% and 25.44% were, respectively, achieved in 4T and 2T all-inorganic perovskite/silicon mechanically tandem devices.

TbCl3对高效全无机钙钛矿/硅串联太阳能电池的界面调节

镧系化合物TbCl3提高了Me-4PACz的润湿性，进一步促进了结晶，其中Cl−离子钝化了碘空位，提高了埋藏界面处的能级排列。采用TbCl3制备的倒装CsPbI3 PSCs效率高达18.68%，并提高了其在环境空气中的稳定性。在4T和2T全无机钙钛矿/硅机械串联器件中，效率分别达到29.40%和25.44%。

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
