Abstract

Abstract Organometallic halide perovskite materials have attracted great attention in the past few years owing to their excellent optical properties and solution-processable fabrication. However, the further development of these lead-based materials is restricted by the toxic heavy-metal element Pb. Herein, we present a dissolution-recrystallization method to fabricate high-quality lead-free Cs3Bi2I9 perovskite nanosheets film and further explore its potential application in solar cells with three different kinds of hole transport materials. The solar cells based on ultrathin Cs3Bi2I9 nanosheets show remarkable improvement in the photovoltaic performance and a high power conversion efficiency of 3.20% has been achieved in the solar cell with CuI as the hole transport material, which is the highest efficiency value of Bi-based perovskite solar cells that has been reported so far. The Cs3Bi2I9 nanosheets based solar cell with CuI also showed a long-term stability in ambient air. These encouraging results of our work demonstrate the possibility of further improvement of the performance of lead-free perovskite solar cells.

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.
