New world record for direct solar water-splitting efficiency
5 Jul 2018 at 8:40am
An international team of researchers has now succeeded in raising the efficiency of producing hydrogen from direct solar water-splitting to a record 19 per cent. They did so by combining a tandem solar cell of III-V semiconductors with a catalyst of rhodium nanoparticles and a crystalline titanium dioxide coating.
Bacteria-powered solar cell converts light to energy, even under overcast skies
5 Jul 2018 at 5:42am
Researchers have found a cheap, sustainable way to build a solar cell using bacteria that convert light to energy. Their cell generated a current stronger than any previously recorded from such a device, and worked as efficiently in dim light as in bright light. This innovation could be a step toward wider adoption of solar power in places like British Columbia and parts of northern Europe where overcast skies are common.
Material could help windows both power your home and control its temperature
3 Jul 2018 at 8:28am
Environmentally friendly building trends have boosted the popularity of window coatings that keep heating and cooling costs down by blocking out unneeded parts of sunlight. They have also inspired scientists and engineers to create thin, see-through solar cells to turn windows into miniature electricity generators. Researchers have gone a step further and combined these two functions into one window-compatible material that could double the energy efficiency of an average household.
