Herein, we have developed an integrated photoanode for solar water splitting based on an ‘‘Earthabundant’’ Ni–Fe based electrocatalyst combined with a versatile multijunction Si-based photovoltaic
device, designed in such a way to allow a direct coupling with the electrocatalyst with minimal losses.
The water oxidation catalyst was prepared by electrochemical deposition of iron on a nickel foil,
followed by thermal annealing, leading to the formation of NiO, a-Fe2O3, and NiFe2O4 phases. Detailed
structural and surface characterization revealed the effect of the addition of different Fe contents and
the subsequent implications on the electrocatalytic performance. The optimized integrated photoanode
delivered a maximum photocurrent density of 6.2 mA cm2 at 0 V applied bias, which corresponds to a
7.7% of Solar-To-Hydrogen conversion efficiency, which remained stable for more than 20 hours. These
results pave the way towards large-scale, efficient and low-cost solar energy conversion solutions based
on non-critical raw materials. [-]
