Inner‐Sphere Nitrate Enables Highly Stable Aqueous NiO x Nanoparticle Inks and Promotes Phosphonic‐Acid SAM Anchoring for Efficient Inverted Perovskite Solar Cells

ABSTRACT Aqueous processing of NiO x nanoparticle (NP) hole‐selective layers suffers from a narrow precipitation window, poor colloidal stability, and poorly controlled surface chemistry that hampers the adsorption of phosphonic‐acid self‐assembled monolayers (SAMs). Here we intr...
