" ... one potential route to simplifying things down: it might be
possible to get rid of the photovoltaics entirely", " ... the cobalt
phosphate catalyst can be made to form directly on the surface of a
photovoltaic material, where it harvests the charge differences
directly, rather than requiring that they be piped in as current from
an external source."
"The research was done with a rather unusual photovoltaic material:
zinc oxide, better known as a component of some sunblocks."
" ... the whole process of harvesting the charge separation, with its
associated equipment and cost, could be done without—if the cobalt
catalyst was placed in close enough proximity to the zinc oxide, it
could directly harvest the charge differential from the surface to
split water."
