Solar Hydrogen Fuel Generation


Project Description

The expected depletion of fossil fuel reserves and its severe environmental impact have emphasized the need for sustainable and clean energy resources. Solar hydrogen fuel generation by water splitting using sunlight, water, 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, solar hydrogen production via water splitting 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 regard, extensive research efforts have been devoted to address these challenges.In this project,our goal is to fabricate a stable semiconductor photoelectrode that can absorb the visible light as well as produce a high rate of hydrogen fuel. The student engaged to this research activity will be able to receive a high-quality training and gain a valuable experience in the field of semiconductor nanostructures fabrication and the solar hydrogen generation, which can help his future career significantly in the academic and the industrial fields.​ ​​​​​​
