TL;DR: In this paper, the authors evaluated the solar-to-hydrogen (STH) efficiency limits, along with the maximum efficiency values and the corresponding optimal band gap combinations, for various combinations of light absorbers arranged in a tandem configuration in realistic, operational water splitting prototypes.

TL;DR: In this article, a critical look at the progress in incorporating electrochemical CO2 reduction catalysts into practical device architectures that operate using vapor-phase CO2 reactants, thereby overcoming intrinsic limitations of aqueous-based systems.

TL;DR: Lithographically patterned nanowire electrodeposition (LPNE) combines attributes of photolithography with the versatility of bottom-up electrochemical synthesis as discussed by the authors, which is employed to define the position of a sacrificial nanoband electrode, preferably formed from a metal such as nickel, copper, silver, gold or the like, which is stripped using electrooxidation or a chemical etchant.

TL;DR: In this paper, a monolithically integrated device consisting of a tandem-junction GaAs/InGaP photoanode coated by an amorphous TiO2 stabilization layer was used to effect unassisted, solar-driven water splitting in 1.0 M KOH(aq).

TL;DR: A validated multi-physics numerical model that accounts for charge and species conservation, fluid flow, and electrochemical processes has been used to analyze the performance of solar-driven photoelectrochemical water-splitting systems as mentioned in this paper.
