abstract = {Photoelectrochemical water splitting promises both
sustainable energy generation and energy storage in the form
of hydrogen. However, the realization of this vision
requires laboratory experiments to be engineered into a
large-scale technology. Up to now only few concepts for
scalable devices have been proposed or realized. Here we
introduce and realize a concept which, by design, is
scalable to large areas and is compatible with multiple
thin-film photovoltaic technologies. The scalability is
achieved by continuous repetition of a base unit created by
laser processing. The concept allows for independent
optimization of photovoltaic and electrochemical part. We
demonstrate a fully integrated, wireless device with stable
and bias-free operation for 40 h. Furthermore, the concept
is scaled to a device area of 64 cm2 comprising 13 base
units exhibiting a solar-to-hydrogen efficiency of $3.9\%.$
The concept and its successful realization may be an
important contribution towards the large-scale application
of artificial photosynthesis.},
