Engineers have discovered a new way to manufacture solar cells using perovskite semiconductors. It could lead to lower-cost, more efficient systems for powering homes, cars, boats and drones.
The solar energy world is ready for a revolution. Scientists are racing to develop a new type of solar cell using materials that can convert electricity more efficiently than today's panels., a University of Colorado Boulder researcher and his international collaborators unveiled an innovative method to manufacture the new solar cells, known as perovskite cells, an achievement critical for the commercialization of what many consider the next generation of solar technology.
"Perovskites might be a game changer," said Michael McGehee, a professor in the Department of Chemical and Biological Engineering and fellow with CU Boulder's Renewable & Sustainable Energy Institute. "This is fine at the research stage. But when you start coating large pieces of glass, it gets harder and harder to do this in a nitrogen filled box," McGehee said.
"It's too early to say that they are as stable as silicon panels, but we're on a good trajectory toward that," McGehee said. With higher efficiency and potentially lower price tags, these tandem cells could have broader applications than existing silicon panels, including potential installation on the roofs of electric vehicles. They could add 15 to 25 miles of range per day to a car left out in the sun, enough to cover many people's daily commutes. Drones and sailboats could also be powered by such panels.

Engineers in Nepal Use Eco-Bricks to Rebuild with Less Air PollutionEngineers and entrepreneurs in Nepal are using a different kind of brick to rebuild the country using a process that produces less carbon and other air pollution. The technology, called 'compressed stabilized earth bricks,' has a proven record for its strength and also reduces air pollution compared to conventional brick kilns. This alternative is gaining popularity as people recognize the benefits of eco-bricks, especially in disaster-prone or rural areas where building costs are high. Construction costs can be reduced by up to 25 percent with this technology.
