"These results are particularly encouraging since they were achieved using a new class of metamorphic semiconductor materials, allowing much greater freedom in multijunction cell design for optimal conversion of the solar spectrum," said Dr. This technology will continue to dramatically reduce the cost of generating electricity from solar energy as well as the cost of materials used in high-power space satellites and terrestrial applications. High efficiency multijunction cells have a significant advantage over conventional silicon cells in concentrator systems because fewer solar cells are required to achieve the same power output. So, once qualified, they can be manufactured in very high volumes with minimal impact to production flow."
"The terrestrial cell we have developed uses the same technology base as our space-based cells. David Lillington, president of Spectrolab. "This solar cell performance is the highest efficiency level any photovoltaic device has ever achieved," said Dr. Department of Energy's National Renewable Energy Laboratory (NREL) in Golden, Colo., verified the milestone. Using concentrated sunlight, Spectrolab demonstrated the ability of a photovoltaic cell to convert 40.7 percent of the sun's energy into electricity.
