Additive-Modulated Evolution of HC(NH2)2PbI3 Black Polymorph for Mesoscopic Perovskite Solar Cells
Abstract
Formamidinium lead triiodide (HC(NH 2 ) 2 PbI 3 or FAPbI 3 ) is gaining increasing interest in the field of mesoscopic perovskite solar cells (PSCs) for its broader light absorption compared with the more widely studied CH 3 NH 3 PbI 3 (MAPbI 3 ). Because FAPbI 3 has two polymorphs (“black” α-FAPbI 3 and “yellow” δ-FAPbI 3 ) at ambient temperature, where α-FAPbI 3 is the desirable photoactive perovskite phase, it becomes particularly important to suppress the formation of the nonperovskite δ-FAPbI 3 for achieving high efficiency in FAPbI 3 -based mesoscopic PSCs. In this study, we demonstrate that the judicious use of low-volatility additives in the precursor solution assists in the evolution of α-FAPbI 3 through the formation of non-δ-FAPbI 3 intermediate phases, which then convert to α-FAPbI 3 during thermal annealing. The underlying mechanism involved in the additive-modulated evolution of α-FAPbI 3 upon mesoporous TiO 2 substrates is elucidated, which suggests guidelines for developing protocols for the fabrication efficient FAPbI 3 -based mesoscopic PSCs.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
