New Energy Technologies Inc developed an organic solar array that is both transparent and produces electricity. They made use of conductive polymers, a thousand times thinner than human hair, assembled them together, and - voilÃƒÆ’ ! Here's a working solar cell less then 1/4 the size of a grain of rice, producing electricity just like its big silicon brother, only cheaper.
