摘要

在退火过程中，水分促进了钙钛矿的结晶，但只有在一个狭窄的湿度范围内，阻碍了钙钛矿太阳能电池的稳定批量生产，特别是对于甲脒碘化铅。为了克服这个问题，我们在钙钛矿薄膜中集成了一个“结晶活化的水分屏障”，在初始退火过程中，它可以以液态/结晶阶段存在，允许水分进入并促进结晶，然后向上迁移，并在薄膜表面形成致密的疏水层，以保护钙钛矿免受高湿度造成的损害。这种“防潮屏障”使钙钛矿薄膜的制造对从20%到90%以上的相对湿度范围不敏感。屏障还可以调节大块结晶和钝化表面缺陷。结晶激活的水分屏障有效地降低了钙钛矿薄膜在退火过程中对湿度的敏感性，为高耐受性钙钛矿光伏器件的制造铺平了道路。

Crystallization-activated moisture barrier for high-tolerance manufacturing of perovskite solar cells

Moisture promotes perovskite crystallization during annealing but only within a narrow humidity range, hindering the stable mass production of perovskite solar cells, especially for formamidinium lead iodide. To overcome this, we integrated a “crystallization-activated moisture barrier” into the perovskite film, which can exist in a liquid state/crystallization phase during the initial annealing to allow moisture to enter and promote crystallization, then migrate upward, and form a dense hydrophobic layer on the film surface to protect the perovskite from high humidity–caused damage. Such a “moisture barrier” enables the manufacturing of perovskite films to be insensitive to a wide range of relative humidity from 20% to over 90%. The barrier also regulates bulk crystallization and passivates surface defects. The crystallization-activated moisture barrier effectively reduces the sensitivity of perovskite films to humidity during annealing, which paves the way for high-tolerance manufacturing of perovskite photovoltaic devices.
