An efficient and stable photoelectrochemical system with 9% solar-to-hydrogen conversion efficiency via InGaP/GaAs double junction

Photoelectrochemical water-splitting devices with III-V semiconductors are efficient for solar-to-hydrogen conversion, but high costs and poor stability limit applications. Here, authors decouple light harvesting from electrolysis to enhance stability without compromising the efficiency.
