Throughout decades of research on solar cells, one formula has been considered an absolute limit to the efficiency of such devices in converting sunlight into electricity: Called the Shockley-Queisser efficiency limit, it posits that the ultimate conversion efficiency can never exceed 34 percent for a single optimized semiconductor junction. Now, researchers at MIT have shown that there is a way to blow past that limit as easily as today's jet fighters zoom through the sound barrier...

U.S. scientists develop novel windows to channel solar energy WASHINGTON, July 10 (Xinhua) -- Imagine windows that not only provide a clear view and illuminate rooms, but also use sunlight to efficiently help power the building, according to a report by Engineers at Massachusetts Institute of Technology (MIT). The work, appearing in the July 11 issue of the journal Science, involves the creation of a novel "solar concentrator.""Light is collected over a large area (like a window) and...
