摘要

本文描述了一种新的策略，通过仔细控制吸收器内的内置电场来进一步提高无铅锡钙钛矿太阳能电池的效率。基于垂直Sn2+梯度和增强电场的formamidium tin ioide (FASnI3)钙钛矿太阳能电池的效率达到了13.82%。具有非均质FASnI3吸收剂的太阳能电池具有超高稳定性，在空气中1个太阳照射1000小时后保持超过13%的效率。

Heterogeneous FASnI3 Absorber with Enhanced Electric Field for High-Performance Lead-Free Perovskite Solar Cells

Highlights

A novel strategy to further improve the efficiency of lead-free tin perovskite solar cells by carefully controlling the built-in electric field in the absorber is described.
A promising efficiency of 13.82% was obtained based on the formamidinium tin iodide (FASnI₃) perovskite solar cells with a vertical Sn²⁺ gradient and an enhanced electric field.
The solar cell with a heterogeneous FASnI₃ absorber is ultrastable, maintaining over 13% efficiency after operation under 1-sun illumination for 1,000 h in air.

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.
