The Inside Cover illustrates the cross‐sectional sketch of a hybrid photovoltaic/photoelectrochemical (PV/PEC) water‐splitting device with a benchmark solar‐to‐hydrogen conversion efficiency of 5.2 % under simulated air mass (AM) 1.5 illumination. The cell consists of a gradient‐doped tungsten–bismuth vanadate (W:BiVO 4 ) photoanode and a thin‐film silicon solar cell. This record efficiency for metal oxide‐based water‐splitting devices is reached by further optimization of the doping profile in the W:BiVO 4 photoanode as well as the smart design of the micromorph silicon (a‐Si:H/nc‐Si:H) cell. More details can be found in the Full Paper by Han et al. on page 2832 (DOI: 10.1002/cssc.201402456 ).
