Abstract

Highlights

A self-buffered molecular migration strategy is developed to suppress spontaneous intermolecular exchange between perovskite intermediate phase and ambient moisture.
Exceptionally broad nucleation time and humidity tolerance windows are achieved for perovskite crystallization under ambient air conditions. 1.68 eV-bandgap perovskite solar cells (PSCs) reach a record efficiency of 22.09% when processed in 50–60% relative humidity.
The strategy is broadly applicable to 1.53 eV- and 1.77 eV-bandgap perovskite films, enabling high-efficiency PSCs via air-based crystallization processing.

基于自缓冲分子迁移策略的钙钛矿薄膜的耐湿可扩展环境空气结晶

开发了一种自缓冲分子迁移策略来抑制钙钛矿中间相与环境水分之间的自发分子间交换。在环境空气条件下，钙钛矿结晶实现了异常宽的成核时间和湿度耐受窗口。1.68 ev -带隙钙钛矿太阳能电池（PSCs）在50-60%的相对湿度下加工时，效率达到创纪录的22.09%。该策略广泛适用于1.53 eV和1.77 eV带隙钙钛矿薄膜，通过空气基结晶工艺实现高效的PSCs。

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.
