Abstract
This work demonstrates that ultrathin (4 nm) tungsten oxide (WO3) coatings on copper gallium selenide (CuGa3Se5) photocathodes have the potential for long-term solar hydrogen evolution. With a combination of a robust 1.84 eV CuGa3Se5 absorber layer, a WO3 protective coating, and a Pt catalyst, we obtain a new durability milestone for any non-silicon photoelectrochemical hydrogen-producing device by passing 21 490 C cm−2 of charge across six weeks of continuously-illuminated chronoamperometric testing under applied bias.
