Solar Impulse 2 to make New York fly-over
2016-06-11 05:23:00| Climate Ark Climate Change & Global Warming Newsfeed
BBC: The solar-powered plane Solar Impulse has arrived at New York's JFK airport after making the short trip from Lehigh Valley in Pennsylvania. Taking off late on Friday night local time, the aircraft spent a good part of the journey turning around the Statue of Liberty for a photoshoot. This latest flight marks the completion of the trans-America portion of the quest to circle the globe on no fuel. Solar Impulse must now prepare for a daunting crossing of the Atlantic.

Perovskite solar cells surpass 20 percent efficiency
2016-06-09 22:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: EPFL researchers are pushing the limits of perovskite solar cell performance by exploring the best way to grow these crystals. Michael Graetzel and his team found that, by briefly reducing the pressure while fabricating perovskite crystals, they were able to achieve the highest performance ever measured for larger-size perovskite solar cells, reaching over 20% efficiency and matching the performance of conventional thin-film solar cells of similar sizes. Their results are published in Science. ...

How to Overcome the Greatest Barriers to Rooftop Solar Power
2016-06-09 08:11:00| Climate Ark Climate Change & Global Warming Newsfeed
Scientific American: For consumers looking for cheaper, cleaner, and more local electricity generation, rooftop solar is a promising option. But even as installation costs continue to fall, the growth of distributed solar is threatened by other financial and technical barriers. Typical net metering rate structures can make it impossible for electricity providers to recover their costs in markets with a large penetration of rooftop solar. Meanwhile, solar panels can be prohibitively expensive to purchase. Even solar leasing...
