In article number 2001759, Kilwon Cho and co‐workers report the novel design of an organic spacer as a multifunctional additive for formamidinium lead tri‐iodide (FAPbI₃) perovskite solar cells. Low dimensional (LD) perovskites assembled by organic spacers not only protect the grain boundary of FAPbI₃ from moisture but also facilitate the nucleation and growth of FAPbI₃ at low temperature. An LD/ FAPbI₃ composite based solar cell exhibits power conversion efficiency of 21.25% retaining 80% of the initial efficiency after 500 hours without encapsulation.

钙钛矿太阳能电池：有机间隔基阳离子的分子工程，用于高效稳定的甲ami钙钛矿太阳能电池（Adv。Energy Mater。42/2020）

在Kilwon Cho及其同事的文章编号2001759中，他报告了一种新颖的有机间隔基设计，该结构用作三碘化甲酸铵铅（FAPbI ₃）钙钛矿太阳能电池的多功能添加剂。由有机间隔物组装而成的低尺寸钙钛矿不仅保护FAPbI ₃的晶界免受潮气，而且还促进了FAPbI ₃在低温下的成核和生长。基于LD / FAPbI ₃复合材料的太阳能电池在没有封装的情况下，在500小时后的功率转换效率为21.25％，保持了初始效率的80％。
