摘要

苯并脒衍生物被用来区分二维钝化和非晶钝化。在倒置钙钛矿太阳能电池中引入n型二维钝化层，增强了电荷的提取和输运，减少了界面复合。有机配体的分子内电荷是在三维钙钛矿层上形成二维晶体盖层的关键。由于三维钙钛矿通过晶体二维封盖的疏水密封，提高了倒置钙钛矿太阳能电池的长期稳定性。

Differentiating the 2D Passivation from Amorphous Passivation in Perovskite Solar Cells

Highlights

Benzamidine derivatives are utilized to differentiate between 2D passivation and amorphous passivation.
Introducing an n-type 2D passivation layer enhances the charge extraction and transportation and reduces the interface recombination in inverted perovskite solar cells.
The intramolecular charge of organic ligands is critical for the formation of crystalline 2D capping layers on 3D perovskite layers.
The long-term stability of inverted perovskite solar cells is improved owing to hydrophobic sealing of 3D perovskite via crystalline 2D capping.

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.
