IBM Research Unveils Breakthrough In Solar Farm Technology "Liquid Metal" at the Center of IBM Innovation to Significantly Reduce Cost of Concentrator Photovoltaic Cells ARMONK, NY - 15 May 2008: IBM (NYSE: IBM) today announced a research breakthrough in photovoltaics technology that could significantly reduce the cost of harnessing the Sun's power for electricity. By mimicking the antics of a child using a magnifying glass to burn a leaf or a camper to start a fire, IBM scientists are using a large lens to concentrate the Sun's power, capturing a record 230 watts onto a centimeter square solar cell, in a technology known as concentrator photovoltaics, or CPV. That energy is then converted into 70 watts of usable electrical power, about five times the electrical power density generated by typical cells using CPV technology in solar farms. <more>
