AB - We demonstrate that the addition of an intrinsic GaAs shell to form a p-i-n junction with GaAs/GaAs/AlGaAs core/shells nanowire (NW) enhances the photocurrent density by fivefold compared to a conventional p-n junction with GaAs/AlGaAs NW. The GaAs/AlGaAsmaterial system offers distinct advantages due to its strong visible-light absorption, tunable bandstructure, and compatibility with protective and catalytic overlayers, such as TiO2, which can enhance surface stability and charge separation. What we believe to be a novel photocathode structure demonstrates a one-sun photocurrent density of 0.542 mA/cm2 at an applied potential of 0.20V with respect to the reversible hydrogen electrode (RHE). This work demonstratesthe suitability of GaAs/GaAs/AlGaAs p-i-n core/shells NWs for PEC water splitting and their potential for green hydrogen production.
