Lasers are making solar cells competitive

Solar electricity has a future: It is renewable and available in unlimited quantities, and it does not produce any gases detrimental to the climate. Its only drawback right now is the price: the electric power currently being produced by solar cells in northern Europe must be subsidised if it is to compete against the household electricity generated by traditional power plants. At 'Laser 2009' in Munich, 15 to 18 June, Fraunhofer researchers will be demonstrating how laser technology can contribute to optimising the manufacturing costs and efficiency of solar cells...
