Stabilized Wide Bandgap Perovskite Solar Cells by Tin Substitution
Open accessAbstract
Wide bandgap MAPb(I 1– y Br y ) 3 perovskites show promising potential for application in tandem solar cells. However, unstable photovoltaic performance caused by phase segregation has been observed under illumination when y is above 0.2. Herein, we successfully demonstrate stabilization of the I/Br phase by partially replacing Pb 2+ with Sn 2+ and verify this stabilization with X-ray diffractometry and transient absorption spectroscopy. The resulting MAPb 0.75 Sn 0.25 (I 1– y Br y ) 3 perovskite solar cells show stable photovoltaic performance under continuous illumination. Among these cells, the one based on MAPb 0.75 Sn 0.25 (I 0.4 Br 0.6 ) 3 perovskite shows the highest efficiency of 12.59% with a bandgap of 1.73 eV, which make it a promising wide bandgap candidate for application in tandem solar cells. The engineering of internal bonding environment by partial Sn substitution is believed to be the main reason for making MAPb 0.75 Sn 0.25 (I 1– y Br y ) 3 perovskite less vulnerable to phase segregation during the photostriction under illumination. Therefore, this study establishes composition engineering of the metal site as a promising strategy to impart phase stability in hybrid perovskites under illumination.

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.
