Scanning atmospheric-pressure plasma jet (APPJ) treatment of nickel oxide with a peak temperature of 500 °C was performed for fabricating p-i-n structure perovskite solar cells (PSCs). APPJ post-treatment increases the haze of NiO on FTO glass, leading to enhanced light scattering in PSCs that in turn improves the cell efficiency. APPJ treatment on NiO also improves the wettability to facilitate the follow-up deposition of CHNHPbI. This also leads to better PSC performance. X-ray photoelectron spectroscopy indicates that APPJ treatment results in fewer C-N bonds and reduced NiAc content, suggesting more complete conversion of the liquid precursor into NiO. With three APPJ scans, the average PCE improves from 11.91% to 13.47%, with the best-performing PSC achieving an efficiency of 15.67%.
采用扫描大气压等离子体射流（APPJ）对氧化镍进行处理，峰值温度为500°C，用于制备p-i-n结构的钙钛矿太阳能电池（PSC）。APPJ后处理增加了FTO玻璃上NiO的雾度，导致PSC中的光散射增强，进而提高了电池效率。对NiO进行APPJ处理还提高了润湿性，便于后续CHNHPbI的沉积。这也带来了更好的PSC性能。X射线光电子能谱表明，APPJ处理导致C-N键减少，NiAc含量降低，表明液体前驱体向NiO的转化更完全。经过三次APPJ扫描，平均光电转换效率从11.91%提高到13.47%，性能最佳的PSC效率达到15.67%。
