Abstract
Sb<sub>2</sub>Se<sub>3</sub>nanorod arrays were modified with an n-type In<sub>2</sub>S<sub>3</sub>layer and a layer of molybdenum sulfide catalyst to form p–n heterojunction photocathodes. A photocurrent of −27 mA cm<sup>−2</sup>with a solar-to-hydrogen conversion efficiency of 2.6% can be obtained.
