Concentrated Solar Light Photoelectrochemical Water Splitting for Stable and High-Yield Hydrogen Production.

ABSTRACT: Photoelectrochemical water splitting is a promising technique for converting solar energy into low-cost and eco-friendly H₂ fuel. However, the production rate of H₂ is limited by the insufficient number of photogenerated charge carriers in the conventional photoelectrodes under 1 sun (100 mW cm^-2) light. Concentrated solar light irradiation can overcome the issue of low yield, but it leads to a new challenge of stability because the accelerated reaction alters the surface chemical composition of photoelectrodes. Here, it is demonstrated that loading Pt nanoparticles (NPs) on single crystalline GaN nanowires (NWs) grown on n⁺-p Si photoelectrode operates efficiently and stably under concentrated solar light. Although a large number of Pt NPs detac
