Solar Energy Cells Made of Everyday Plastic. In research published today in Nature Materials magazine, [several researchers] showcase their work on an innovative new plastic (or polymer) solar cell they hope eventually can be produced at a mere 10 percent to 20 percent of the current cost of traditional cells, making the technology more widely available. The price for quality traditional solar modules typically is around three to four times more expensive than fossil fuel. Independent tests on the UCLA solar cell already have received high marks. The nation's only authoritative certification organization for solar technology, the National Renewable Energy Laboratory (NREL), located in Golden, Colo., has helped the UCLA team ensure the accuracy of their efficiency numbers. The plastic solar cell is still a few years away from being available to consumers, but the UCLA team is working diligently to get it to market.
