Controlled n‐Doping in Air‐Stable CsPbI2Br Perovskite Solar Cells with a Record Efficiency of 16.79%
Abstract
Cesium‐based inorganic perovskites, such as CsPbI 2 Br, are promising candidates for photovoltaic applications owing to their exceptional optoelectronic properties and outstanding thermal stability. However, the power conversion efficiency of CsPbI 2 Br perovskite solar cells (PSCs) is still lower than those of hybrid PSCs and inorganic CsPbI 3 PSCs. In this work, passivation and n‐type doping by adding CaCl 2 to CsPbI 2 Br is demonstrated. The crystallinity of the CsPbI 2 Br perovskite film is enhanced, and the trap density is suppressed after adding CaCl 2. In addition, the Fermi level of the CsPbI 2 Br is changed by the added CaCl 2 to show heavy n‐type doping. As a result, the optimized CsPbI 2 Br PSC shows a highest open circuit voltage of 1.32 V and a record efficiency of 16.79%. Meanwhile, high air stability is demonstrated for a CsPbI 2 Br PSC with 90% of the initial efficiency remaining after more than 1000 h aging in air.

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.
