Abstract

Sunlight absorption in water has a critical impact on solar fuel generation by direct photoelectrolysis because devices are commonly illuminated through the aqueous electrolyte. We show the relevant reference spectra, calculate fundamental solar-to-hydrogen efficiency prospects, and discuss the design implications for unassisted solar water-splitting devices.
