Due to the diminishing availability of fossil fuels, the creation of alternative, clean, and renewable fuels is now essential. A sustainable, environmentally friendly alternative to fossil fuels for a range of uses is solar hydrogen produced from water (e.g., transport, power generation, and industrial energy). However, cost-effective, efficient, and stable production of hydrogen fuel from water is a challenge for real-world application. In an effort to provide a current description of photo electro chemical (PEC) water splitting methods, large-scale commercialization (such as photo production) of hydrogen from water has been sought after. Solar hydrogen synthesis using semiconductor photo electrodes (PEs) is viewed as a very efficient solution in this area.

The issue will be focused on the recent developments in the field of hydrogen fuel cells employing low-cost semiconducting materials.

Specific aims of the special issue will be:

(1) Cathodic materials for efficient hydrogen production by photo electro chemical cell.

(2) Photovoltaic hydrogen evolution via water splitting.

(3) Cost effective synthesis of semiconducting materials

(4) Solar Energy for hydrogen evolution reactions

(5) Hydrogen Fuel Cells – A clean energy alternate to fossil fuels
