Scientists at the University of California, Berkeley, are working on nanopillar solar cells that could cut the cost of solar power to a third of the current levels. More info at DailyTech.
Now University of California, Berkeley researchers have created a new type of solar cells that may offer exactly that -- lots of solar energy with low processing and materials costs. The new type of solar cells are composed of tiny nanopillars in a thin film layer atop aluminum foil. The foil is enclosed in a protective layer of transparent, rubbery polymer.
