The principles of photoelectrochemical generation of hydrogen using inorganic semiconductor/water interfaces are first outlined. Advantages in the use of oxide semiconductors for solar hydrogen generation are then enumerated. The requirements for the water splitting reaction in terms of the semiconductor photocatalyst(s) are then elaborated. Finally, preliminary results are presented on the use of electrodeposited p-Cu2O films for hydrogen generation in a twin-compartment photoelectrochemical cell using visible light and sacrificial reducing agents in the (dark) anode compartment.

AbstractA highly efficient, low-cost and environmentally friendly photocathode with long-term stability is the goal of practical solar hydrogen evolution applications. Here, we found that the Cu3BiS3 film-based photocathode meets the abovementioned requirements. The Cu3BiS3-based photocathode presents a remarkable onset potential over 0.9 VRHE with excellent photoelectrochemical current densities (~7 mA/cm2 under 0 VRHE) and appreciable 10-hour long-term stability in neutral water solutions. This high onset potential of the Cu3BiS3-based photocathode directly results in a good unbiased operating photocurrent of ~1.6 mA/cm2 assisted by the BiVO4 photoanode. A tandem device of Cu3BiS3-BiVO4 with an unbiased solar-to-hydrogen conversion efficiency of 2.04% is presented. This tandem device also presents high stability over 20 hours. Ultimately, a 5 × 5 cm2 large Cu3BiS3-BiVO4 tandem device module is fabricated for standalone overall solar water splitting with a long-term stability of 60 hours.
