摘要

通过引入有机-无机CL-NH配合物作为多功能界面层，实现了高性能钙钛矿太阳能电池。CL-NH配合物不仅可以减少SnO2表面的氧空位，还可以调节薄膜结晶，器件效率达到23.69%。该器件具有优异的稳定性，在500 h光照后仍保持91.5%的初始功率转换效率。

Synergistic Optimization of Buried Interface by Multifunctional Organic–Inorganic Complexes for Highly Efficient Planar Perovskite Solar Cells

Highlights

Highly performed perovskite solar cells are achieved via introducing organic–inorganic CL–NH complex as multifunctional interfacial layer.
CL–NH complex not only reduces oxygen vacancies on the surface of SnO₂ but also regulates film crystallization, resulting in a superior device efficiency of 23.69%.
The resulting device performs excellent stability with 91.5% initial power conversion efficiency retained after 500 h light illumination.

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary and open-access journal that focus on science, experiments, engineering, technologies and applications of nano- or microscale structure and system in physics, chemistry, biology, material science, pharmacy and their expanding interfaces with at least one dimension ranging from a few sub-nanometers to a few hundreds of micrometers. Especially, emphasize the bottom-up approach in the length scale from nano to micro since the key for nanotechnology to reach industrial applications is to assemble, to modify, and to control nanostructure in micro scale. The aim is to provide a publishing platform crossing the boundaries, from nano to micro, and from science to technologies.
