Transparent solar technology represents ‘wave of the future’

According to a new research report published in Nature Energy, See-through solar materials that can be applied to windows represent a massive source of untapped energy and could harvest as much power as bigger, bulkier rooftop solar units. Led by engineering researchers at Michigan State University, the authors argue that widespread use of such highly … Continue reading “Transparent solar technology represents ‘wave of the future’”

MIT’s new flow battery breathes air to cut costs of renewable energy storage

Wind and solar power are increasingly popular sources for renewable energy. But intermittency issues keep them from connecting widely to the U.S. grid: They require energy-storage systems that, at the cheapest, run about $100 per kilowatt hour and function only in certain locations. Now MIT researchers have developed an “air-breathing” battery that could store electricity … Continue reading “MIT’s new flow battery breathes air to cut costs of renewable energy storage”

A solar cell you can put in the wash

Scientists from RIKEN and the University of Tokyo have developed a new type of ultra-thin photovoltaic device, coated on both sides with stretchable and waterproof films, which can continue to provide electricity from sunlight even after being soaked in water or being stretched and compressed. The work, published in Nature Energy, could open the way to … Continue reading “A solar cell you can put in the wash”

Solar Impulse 2 Completes Historic Trip Around The World Without A Drop Of Fuel

The experimental zero-fuel aircraft, Solar Impulse 2, has completed the final leg of its global circumnavigation attempt. It is the first circumnavigation of the world by a piloted fixed-wing aircraft using only solar power. The Solar Impulse prototype has already set eight world records, including first solar aeroplane to fly through the night, between two … Continue reading “Solar Impulse 2 Completes Historic Trip Around The World Without A Drop Of Fuel”

Stanford engineers invent transparent coating that cools solar cells to boost efficiency

Every time you stroll outside you emit energy into the universe: Heat from the top of your head radiates into space as infrared light. Now three Stanford engineers have developed a technology that improves on solar panel performance by exploiting this basic phenomenon. Their invention shunts away the heat generated by a solar cell under … Continue reading “Stanford engineers invent transparent coating that cools solar cells to boost efficiency”
