Perovskite Solar Cells: Molecular Engineering of Organic Spacer Cations for Efficient and Stable Formamidinium Perovskite Solar Cell
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.
