In article number 2000772, Siva Krishna Karuturi, Heping Shen and co‐workers report a perovskite/Si dual absorber tandem cell for stand‐alone solar water splitting. An unprecedented over 17% solar‐to hydrogen conversion efficiency is achieved when a Si photocathode is paired in tandem with a high bandgap (≈1.75 eV) semitransparent perovskite solar cell.
