Production of Solar Fuels Inches Closer with Discovery by Caltech Scientists

Caltech researchers have made a discovery that they say could lead to the economically viable production of solar fuels in the next few years. For years, solar-fuel research has focused on developing catalysts that can split water into hydrogen and oxygen using only sunlight. The resulting hydrogen fuel could be used to power motor vehicles, […]

Transparent solar cells could be massive power source: study

Transparent solar materials applied to windows can harvest as much energy from invisible light waves as bigger, bulkier rooftop solar units, scientists say. Widespread use of such highly transparent solar applications, together with the rooftop units, could drastically reduce the use of fossil fuels. “Highly transparent solar cells represent the wave of the future for […]
