To achieve industrially viable fabrication process for perovskite-based solar cells, every process step must be optimized for maximum throughput. We present a study of substituting laboratory-type UV-Ozone surface treatment with a high-throughput Corona treatment in a scalable perovskite solar cell fabrication process. It is observed that water contact angle measurements provide insufficient information to determine the necessary dose of Corona or UV-Ozone treatment, but the surface carbon signal measured by x-ray photoelectron spectroscopy accurately identifies when surface contamination has been completely removed. Furthermore, we observe highly accelerated de-contamination of ZnO surfaces by UV-Ozone treatment. The effect can be explained by photocatalytic O₂⁻ ion generation indicating that UV-Ozone treatment is also applicable in high-throughput processing.

为了实现钙钛矿基太阳能电池的工业可行制造工艺，必须优化每个工艺步骤以实现最大产量。我们提出了在可扩展钙钛矿太阳能电池制造工艺中用高通量电晕处理代替实验室型UV-臭氧表面处理的研究。可以观察到，水接触角测量无法提供足够的信息来确定电晕或紫外线臭氧处理的必要剂量，但是通过X射线光电子能谱测量的表面碳信号可以准确地识别何时完全去除了表面污染物。此外，我们观察到通过紫外线臭氧处理对ZnO表面的高度加速的去污效果。该效果可以通过光催化ö来解释₂ ^- 离子的产生表明紫外线臭氧处理也适用于高通量处理。
