摘要

我们报告了利用露天刀片涂层作为一种可扩展的方法,通过添加玉米淀粉聚合物添加剂,生产出具有大于 10 倍断裂能的金属卤化物透辉石薄膜,从而获得耐久性和机械稳定性。这就产生了一种可制造的、坚固耐用的过氧化物,其可调厚度超过 10 微米,是目前所报道的溶液加工多晶薄膜的最高值之一。我们发现,淀粉含量的增加会使包晶厚度内的碳分布更加均匀,这可以通过截面元素组成测量来量化。此外,淀粉的加入还带来了有益的薄膜压应力。重要的是,光电特性并没有受到影响,因为随着玉米淀粉的添加量达到 20% (重量百分比),光致发光光谱变得更加均匀。

Open-Air Processing of Mechanically Robust Metal Halide Perovskites with Controllable Thicknesses above 10 µm
We report on the use of open-air blade-coating as a scalable method for producing metal halide perovskite films with >10× fracture energy for durability and mechanical stability through the addition of corn starch polymer additives. This results in a manufacturable and robust perovskite that has tunable thicknesses exceeding 10 µm, among the highest reported values for solution-processed polycrystalline films. We find that an increasing amount of starch causes more uniform carbon distribution within the perovskite thickness as quantified by cross-sectional elemental composition measurements. Further, the incorporation of starch introduces beneficial compressive film stresses. Importantly, the optoelectronic behavior is not compromised, as the photoluminescence spectrum becomes more homogenous with the addition of corn starch up to 20% by weight.
