钙钛矿薄膜后的表面形貌、结晶度和光学性能的变化。结果表明,通过添加少量的PNA可以优化钙钛矿薄膜的性能,其强烈影响薄膜的结晶过程,有助于形成均匀连续的薄膜,减少针孔,从而增强了钙钛矿层的覆盖率和光吸收。当PNA 的含量为1%(质量分数)时,钙钛矿太阳能电池的各项性能最佳,能量转换效率达到了8.38%。与未加PNA 的电池效率(1.31%) 相比,提高了540%。这些结果表明,PNA可以有效调控钙钛矿薄膜的晶体生长和薄膜形貌,在钙钛矿太阳能电池的大规模生产过程中是一种可以改善钙钛矿薄膜质量的有效添加剂。
For perovskite solar cells
the morphology control of the perovskite thin-films is one of the key questions for improving the power conversion efficiency (PCE). To solve this issue

perovskite layers are characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD) and UV-Vis. These experiment results show that the perovskite film properties can be optimized just by combining a small number of PAN

solar cells was increased from 1.31% to 8.13% for the planar cell structure. These results prove that PNA is an effective additive which could improve the quality of perovskite thin-films and potentially be a new candidate as an easily accessible additive during perovskite solar cells mass production.
