abstract = {An all earth-abundant and precious metal-free photocathode
based on a low-temperature fabricated amorphous silicon
tandem junction is demonstrated to be an efficient device
for solar water splitting. With a particular designed Al/Ni
layer stack as photocathode/electrolyte contact an onset
potential for cathodic photocurrent of 1.7 V vs. RHE and a
saturation photocurrent density of 7.2 mA/cm2 were achieved.
For a high-cost alternative with a Ag/Pt layer stack an even
higher photocathode performance is demonstrated. Above all
we present an approach for a dedicated photovoltaic and
electrochemical development for solar water splitting.},
