abstract = {An integrated solar water splitting device based on thin
film silicon multijunction photocathodes is presented. A
graphical representation of the photovoltaic
current–voltage data is introduced which allows for an
estimation of the maximum achievable solar-to-hydrogen
efficiency of the integrated device. Furthermore, a simple
yet very useful series circuit model is used to predict the
photoelectrochemical performance of the integrated device in
a more elaborate way when the j–V characteristics of the
individual components are known. Within the model, the j–V
characteristics of each component can be either modeled with
parameters from the literature or measured. The
photocathode, the electrolyte concentration, and the
hydrogen and oxygen evolving catalysts were varied
exemplarily and the impact of each component on the
integrated device performance was evaluated. A maximum
solar-to-hydrogen efficiency of $9.5\%$ was found using a
triple junction solar cell functionalized with a Pt catalyst
for the hydrogen evolution and a RuO2 catalyst for the
oxygen evolution reaction in a 1 M KOH electrolyte. This
result was confirmed experimentally and is compared to
efficiencies reported in the literature.},
