Built using inexpensive semiconductors, the device packs all components to make hydrogen and can be scaled.
A research team led by Aditya Mohite, a professor of chemical and biomolecular engineering at Rice University in the US, has designed a device that can use sunlight to generate hydrogen, with a record efficiency of 20.8 percent, a press release said.
Hydrogen is being touted as the future of clean energy due to its high energy density that could be deployed even to fly large planes. However, the process of generating hydrogen is currently heavily dependent on fossil fuels. For hydrogen to herald a new future in clean energy, it needs to be produced sustainably and without carbon emissions.
