The expected depletion of fossil fuel reserves and its severe environmental impact have emphasized the need for sustainable and clean energy resources. Solar hydrogen generation from water splitting using sunlight and semiconductors is a promising alternative to conventional fossil fuels, which has great potential to relieve energy and environmental issues and bring an energy revolution in a clean and sustainable manner. To be practical, hydrogen production needs to tackle the challenges of high solar-to-hydrogen (STH) energy conversion efficiency and high stability of the materials and devices. In photoelectrochemical (PEC) water splitting, as an example, the bandgap of semiconductors, band-edge potentials, optoelectronic efficiency, and stability must be satisfied simultaneously to improve the STH efficiency. In this talk, challenges and opportunities for solar hydrogen fuel generation using III-nitride nanostructures will be discussed.
