WebThis study reveals a self-improving behavior of Si/GaN photocathode active for hydrogen production, and sets an investigation paradigm for fundamental understanding of the pivotal role of chemical transformation in PEC water splitting. The gained knowledge from this work can provide feedback to the further optimization of the PEC devices. Webphotocathode were set up by controlling the potential ofthe mesh and ofthe MCP input electrode, on which the photocathode was depos-ited. At the same time, variation ofthe mesh potential during QE measurements allowed us to separately investigate the photocathode response inside the MCP pores and on the interchannel web area. ipl rights 2023
