Solar cells cool themselves to produce more power

BY Jon Fingas   Solar power cells need to stay relatively cool for the sake of both efficiency and longevity, but active cooling (like ventilation) isn’t practical; it’s expensive, and may block the very rays the cells are supposed to collect. To tackle this problem, Stanford University researchers have created a new form of solar […]

Color Solar Panels Let Stained Glass Windows Produce Cheap Power

Because solar panels are designed to accumulate as much light from the sun as possible, they’re typically very dark in color. It makes them more efficient, but also kind of an eyesore, minimizing their adoption. So researchers at the University of Michigan have developed what they believe to be the world’s first semi-transparent, colored solar […]

Amazing Glass that Tints on Demand is now Solar Powered

One of the most exciting products from this year’s Greenbuild expo is SageGlass’ solar-powered windows. Sage’s electrocromic windows can be darkened and lightened to filter the sun’s heat and light according to a room’s needs and the inhabitant’s desires. See a full explanation of the technology here. That takes a small amount of energy, which […]

Nanotech roundup: electricity from sewage, and self-cleaning solar panels

This month’s roundup includes a device for squeezing energy from wastewater, and a coating to keep solar panels clean Poopy Power One resource we are never short of is wastewater. It contains plenty of organic matter that could still produce useful energy, but the challenge is to do this efficiently. An attractive way is to […]

Solar Power Coming To Airplane Windows?

by Pete Danko No, the idea isn’t to power commercial air travel with photovoltaic solar – that’s being left that to super-lightweight, experimental efforts like Solar Impulse. Nevertheless, a French collaboration this week plans to unveil a new way of bringing solar power to aircraft, with a photovoltaic window. The pitch is that it can […]
