Abstract

Abstract : Passivation Agents In article number 2000082, Fei Zhang, Kai Zhu, and co‐workers design a more efficient and stable perovskite solar cell by partially replacing phenylethylammonium (PEA + ) with pentauorophenethylammonium (F5PEA + ) as the 2D perovskite passivation agent by forming a strong noncovalent interaction between the two bulky cations, which enhances charge transport, and presents the highest performance for reported wide‐bandgap perovskite solar cells.
