Abstract. An experimental setup is developed to study the performance of semiconductor photoelectrode hydrogen generator based on gallium nitride. The setup allows simultaneous measurement of the output light flux, photocurrent and photovoltage, the volume of released hydrogen (at the cathode) and oxygen (at the anode).
Keywords: photoelectrolysis of water, hydrogen photogenerators, gallium nitride
