Hydrogen, the most abundant chemical element in the universe, can be harnessed through solar-driven water electrolysis by a photocatalyst material. The project team designed, manufactured, and tested a device in which a photocatalyst material can be mechanically strained to improve its energy conversion efficiency. The device consists of an electrically conductive substrate, a straining mechanism, and a reaction chamber. The electrically conductive substrate, made of a metal-filled polymer, acts as an electrode for the photocatalyst. The straining mechanism was designed to bend this substrate and transfer strain to the photocatalyst over a range of -2 to 2%. The reaction chamber was created to house the substrate and mechanism while allowing light to reach the photocatalyst.
