Band-Aligned Polymeric Hole Transport Materials for Extremely Low Energy Loss α-CsPbI3 Perovskite Nanocrystal Solar Cells
Open accessAbstract
Summary Emerging all-inorganic perovskite nanocrystals can retain a desired crystal structure under ambient conditions and offer easy solution processability. In this work, we have demonstrated CsPbI3 perovskite quantum dot (QD) solar cells with a remarkable efficiency approaching 13% and an extremely low energy loss of 0.45 eV by employing a series of dopant-free polymeric hole-transporting materials (HTMs). The CsPbI3 QD solar cells use polymer HTMs to achieve efficient charge extraction at QD/polymer interfaces and avoid device instability caused by complex doping and oxidation processes required by conventional Spiro-OMeTAD. Meanwhile, the CsPbI3 QD photovoltaic devices can be fabricated at room temperature and exhibit more reproducible film quality, showing potential advantages over current all-inorganic thin-film perovskite solar cells. We believe that our findings will catalyze the development of new device structures, specifically for perovskite QDs, and help realize the promising potential of all-inorganic 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.
