Toward Tandem Solar Cells for Water Splitting Using Polymer Electrolytes
Tandem photoelectrochemical cells,
formed by two photoelectrodes
with complementary light absorption, have been proposed to be a viable
approach for obtaining clean hydrogen. This requires the development
of new designs that allow for upscaling, which would be favored by
the use of transparent polymer electrolyte membranes (PEMs) instead
of conventional liquid electrolytes. This article focuses on the photoelectrochemical
performance of a water-splitting tandem cell based on a phosphorus-modified
α-Fe<sub>2</sub>O<sub>3</sub> photoanode and on an iron-modified
CuO photocathode, with the employment of an alkaline PEM. Such a photoelectrochemical
cell works even in the absence of bias, although significant effort
should be directed to the optimization of the photoelectrode/PEM interface.
In addition, the results reveal that the employment of polymer electrolytes
increases the stability of the device, especially in the case of the
photocathode
