Abstract Surface manipulation of quantum dots (QDs) has been extensively reported to be crucial their performance when applied into optoelectronic devices, especially for photovoltaic devices. In this work, an efficient surface passivation method emerging CsPbI 3 perovskite QDs using a variety inorganic cesium salts (cesium acetate (CsAc), idodide (CsI), carbonate (Cs 2 CO ), and nitrate (CsNO )) is reported.

Abstract To fine‐tune surface ligands towards high‐performance devices, we developed an in situ passivation process for all‐inorganic cesium lead iodide (CsPbI 3 ) perovskite quantum dots (QDs) by using a bifunctional ligand, L‐phenylalanine (L‐PHE). Through the addition of this ligand into precursor solution during synthesis, treated CsPbI QDs display significantly reduced states, increased vacancy formation energy, higher photoluminescence yields, and much improved stability. Consequently,...
