New material increases the lifetime of solar-powered electrons

Nobody wants a laptop computer that stops working when a cloud passes by. Storing sunlight as fuel that can be later used to drive fuel cells requires new materials. Scientists demonstrated such a material. They combined ...

Solar-powered hydrogen production with improved efficiency

Hydrogen could potentially provide a readily available, clean form of energy derived from solar power. To achieve this, scientists need to find a highly efficient, low-cost way of splitting water into its constituent parts ...

Hydrogen for all seasons

Ludwig Maximilian University of Munich chemists have developed novel porous materials called "covalent organic frameworks", which provide a basis for the design of polymeric photocatalysts with tunable physical, chemical ...

Method could make hydrogen fuel cells more efficient

With the growth of wind and solar energy and the increasing popularity of electric vehicles, many people in the U.S. may have forgotten about the promised "hydrogen economy." But in research labs around the world, progress ...

New efficiency record for solar hydrogen production is 14 percent

An international team has succeeded in considerably increasing the efficiency for direct solar water splitting with a tandem solar cell whose surfaces have been selectively modified. The new record value is 14 percent and ...
