Researchers at the University of California, Berkeley, have made a new kind of solar cell by growing an array of upright nanoscale pillars on aluminum foil. They make bendable solar cells by encapsulating the entire cell inside a transparent, rubbery polymer. The design, the researchers suggest, could lead to solar cells that cost less than conventional silicon photovoltaics.
This is the type of renewable energy news I like to see. Scientists working to develop an affordable product with a lot of potential practical applications. Go, you treehuggers, go!
