Herein, the adsorption of alkali metal promoters (Na and K) on the surfaces of face-centered-cubic (FCC) and hexagonal-closest packed (HCP) polymorphous cobalt was systematically investigated using density functional theory. Furthermore, the effect of alkali promoters on surface energies and nanoparticle morphologies was revealed on the basis of Wulff theory. For FCC-Co, the exposed area of the (111) facet in the nanoparticle increases with the adsorption coverage of alkali metal oxide. Meanwhile, the (311), (110), and (100) facets would disappear under the higher adsorption coverage of alkali metals. For HCP-Co, the Wulff morphology is dominated by the (0001) and (<span>(10bar 11)</span>) facets and is independent of the alkali metal adsorption coverage.

Herein, propylamine hydrobromide (PABr) was added to the perovskite precursor solution as an additive to passivate defects and fabricate more uniform and dense perovskite films. Because propylamine cations are too large to enter the perovskite lattices, they only exist at the grain boundary to passivate surface defects and promote crystal growth in a preferred orientation. The PABr additive raises the average short-circuit current density from 19.45 to 25.47 mA·cm<sup>−2</sup> by reducing carrier recombination induced by defects.
