Bipolar Membrane‐Assisted Solar Water Splitting in Optimal pH
Open accessAbstract
An efficient and intrinsically safe bias-free solar-driven water-splitting device composed of perovskite light harvesters, Earth-abundant catalysts, and a bipolar membrane is demonstrated. Overall, 10 mA cm−2 current density with 1.63 V bias voltage for electrochemical water splitting and 12.7% solar to hydrogen conversion efficiency for solar-driven water splitting are achieved.

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.
