Efficient α-CsPbI3 Photovoltaics with Surface Terminated Organic Cations
Open accessAbstract
Summary Quasi-2D or 2D capping is an effective strategy to stabilize organic-inorganic metal halide perovskite materials, often at a detriment to electronic transport. Due to an efficient cation exchange between organic constituents, the location and thickness of reduced-dimensional hybrid perovskite layers is difficult to control. We find that the all-inorganic CsPbI3 perovskite cannot go through either solid state or sequential cation exchange to form a 2D perovskite capping layer. Instead, a defect-passivating organic cation terminated surface is formed that improves phase stability and moisture resistance. The corresponding α-CsPbI3 perovskite solar cells exhibit high reproducibility with a champion stabilized efficiency of 13.5%. This work shows that the high cation exchange resistance of CsPbI3 perovskites can be exploited to promote the development of highly efficient and stable perovskite photovoltaics.

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.
