Abstract

Highlights

The slot-die-coated porous PbI₂:CsI film assisted with nitrogen blowing can promote the rapid and complete transformation of perovskite film.
The crystallinity and morphology of slot-die-coated perovskite film are significantly improved by controlling substrate temperature.
Fully slot-die-coated perovskite solar cells achieve a power conversion efficiency (PCE) of 18.13%, and fully roll-to-roll printed flexible PSCs achieve a PCE of 13.00% in ambient condition.

通过精确控制PbI2:CsI层的形态，实现全卷对卷加工的高效钙钛矿太阳能电池

槽模包覆多孔PbI2:CsI膜辅以氮气吹制，可促进钙钛矿膜的快速完全转化。通过控制衬底温度，可以显著改善钙钛矿薄膜的结晶度和形貌。全槽模涂层钙钛矿太阳能电池的功率转换效率(PCE)为18.13%，全卷对卷印刷柔性PSCs在环境条件下的PCE为13.00%。

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.
