Lead‐free Perovskite Materials (NH4)3Sb2IxBr9−x
Abstract
A family of perovskite light absorbers (NH 4)3 Sb 2 IxBr 9−x (0≤x≤9) was prepared. These materials show good solubility in ethanol, a low‐cost, hypotoxic, and environmentally friendly solvent. The light absorption of (NH 4)3 Sb 2 IxBr 9−x films can be tuned by adjusting I and Br content. The absorption onset for (NH 4)3 Sb 2 IxBr 9−x films changes from 558 nm to 453 nm as x changes from 9 to 0. (NH 4)3 Sb 2 I 9 single crystals were prepared, exhibiting a hole mobility of 4.8 cm 2 V−1 s−1 and an electron mobility of 12.3 cm 2 V−1 s−1. (NH 4)3 Sb 2 I 9 solar cells gave an open‐circuit voltage of 1.03 V and a power conversion efficiency of 0.51 %.

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.
