Abstract
The expected depletion of fossil fuel reserves and its severe environmental impact have brought about the need for sustainable and clean energy resources. Solar hydrogen generation via photoelectrochemical (PEC) water splitting techniques, which combine sunlight, water, and semiconductor materials, are promising alternatives to conventional fossil fuels. Solar-hydrogen fuel produced using PEC methods are renewable, sustainable and environmentally friendly.
Highlights
The expected depletion of fossil fuel reserves and its severe environmental impact have brought about the need for sustainable and clean energy resources
The articles presented in this Feature Issue focus primarily on the studies of direct PEC water splitting techniques using new materials or structures to enhance energy conversion efficiency, and to improve stability
Solar hydrogen production via PEC techniques needs to tackle challenges related to the achievement of high solar-to-hydrogen (STH) energy conversion efficiency, high stability, low cost, and scalability of the hydrogen generation system
