Abstract
Highlights
Alkaline earth cations are successfully incorporated into perovskite lattice with the aid of sulfonic acid anions, while alkaline earth metal halides are lack of doping capacity.
The sulfonic acid anions effectively regulate the crystallization of perovskite and passivate the metallic Pb0 defect states, thereby improving the power conversion efficiency of perovskite solar cells.
By comparing the property of FACF3SO3 and Ca(CF3SO3)2-doped perovskite films, the impact of suppressing halide migration with an activation energy of 1.246 eV is attributed to Ca2+ cations, thus providing methodology for decoupling the effects of cations and anions.
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.
