Enhanced Charge Transport in A-site Ordered Perovskite Derivatives A2A'Bi2I9 (A = Cs; A'= Ag, Cu): A First-Principles Study

Shuhan Li, Siyu Song, Peng Lv +3

Recent experiments have synthesized Cs2AgBi2I9 by partially substituting Cs+ with Ag+ at the A-site of Cs3Bi2I9, resulting in enhanced charge transport properties compared to Cs3Bi…
