A fully integrated solar‐driven water‐splitting system comprised of WO3/FTO/p+n Si as the photoanode, Pt/TiO2/Ti/n+p Si as the photocathode, and Nafion as the membrane separator, was simulated, assembled, operated in 1.0 M HClO4, and evaluated for performance and safety characteristics under dual si...
