Solar Cell Sets World Efficiency Record At 40.8 Percent
It's an "inverted metamorphic triple-junction solar cell". Advances in solar are going the way of computer processor speed and storage and many other information technologies; increasing power, speed and efficiency, decreasing cost, space, waste.
Scientists at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) have set a world record in solar cell efficiency with a photovoltaic device that converts 40.8 percent of the light that hits it into electricity. This is the highest confirmed efficiency of any photovoltaic device to date.
