Here we present an apparatus comprising a photoelectrochemical cell connected a photovoltaic device, comprised of a layer with a thick n-type absorber and a layer comprising a thin p-type hole emitter. The photoelectrochemical cell has binary, metal-oxide semiconductors with wide bandgaps comprising high electron affinities relative to other semiconductor materials allowing for n-type doping.
