Abstract The effect of sulfonation on polysulfone regarding its electrical properties is studied and discussed. In addition to the effect of percentage of sulfonation, the thickness of thin films and the ultraviolet (UV) treatment also were evaluated and reported. The results indicate that percentage of sulfonation is the most important effect, even over thickness. As the sulfonation percentage was increased, better electrical performance (fill factor and power conversion efficiency) was obtained because the sulfonate groups impart a kind of vacancy into the polymer structure, showing comparable energy level to that of conventional poly (3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS). In addition, the UV treatment not only cleans the film's surface but also polarizes the polymeric's surface improving the polysulfone performance, which was 24% better, at least, respect to that obtained without UV treatment. The obtained results open the possibility to optimize sulfonated polysulfones that could be used in inverted hybrid perovskite solar cells.

柔性和意想不到的导电聚砜的磺化及其在钙钛矿太阳能电池中的性能

摘要 研究和讨论了磺化对聚砜电性能的影响。除了磺化百分比的影响外，还评估和报告了薄膜的厚度和紫外线 (UV) 处理。结果表明，磺化百分比是最重要的影响，甚至超过厚度。随着磺化百分比的增加，获得了更好的电性能（填充因子和功率转换效率），因为磺酸盐基团赋予聚合物结构一种空位，显示出与传统聚（3,4-亚乙基二氧噻吩）相当的能级聚苯乙烯磺酸盐 (PEDOT:PSS)。此外，紫外线处理不仅可以清洁薄膜的表面，还可以使聚合物极化 s 表面改善了聚砜的性能，至少比未经紫外线处理的产品好 24%。获得的结果为优化可用于倒置混合钙钛矿太阳能电池的磺化聚砜提供了可能性。
