Orientation-Controlled (h0l) PbI₂ Crystallites Using a Novel Pb-Precursor for Facile and Quick Sequential MAPbI₃ Perovskite Deposition.

ABSTRACT: Organic-inorganic hybrid lead halide perovskites have shown significant progress in the last few years having achieved efficiencies over 25% at the lab scale. The sequential deposition technique has provided a robust approach in the perovskite film fabrication. However, obtaining a reproducible and quality perovskite film has always been challenging because of the highly crystalline and ordered (001) oriented underlying PbI₂ film. Here, we report a simple solution approach to fabricate a PbI₂ residue-free, superior grade perovskite film by using a compositional engineered PbI₂-precursor solution. We demonstrate that the Pb-precursor film crystallized into a R-centered Hexagonal metric lattice with (h0l), (hk0), and (00l) orientat
