Dye-sensitized photoelectrochemical cells (DSPECs) combine high surface area semiconductor electrode supports with molecular chromophores and catalysts to carry out light driven chemical conversions. DSPECs have historically been studied in the context of artificial photosynthesis—water splitting to form oxygen and hydrogen or water oxidation coupled to CO<sub>2</sub> reduction. Recent work has demonstrated that a tandem DSPEC can carry out overall water splitting with the only energy input from absorbed light. Tin oxide has proven an important semiconductor for use in tandem DSPECs and recent advances using unique morphologies of SnO<sub>2</sub>, as well the use of mixed-valence tin oxide, will be discussed. Expanding the utility of DSPECs to catalytic reactions outside of the generation of solar fuels represents an important future direction for this field. To this end, progress in developing a DSPEC for performing light-driven lignin depolymerization will be presented.
