DoE Lab Prototype Sets Record for Solar Cell Efficiency
October 14, 2008 12:23 pm | by by Jason Lomberg, Technical Editor | Blogs | CommentsRegular Efficiency Zone readers know that photovoltaics is a very inefficient technology. While the technology is environmentally-friendly, and the energy source (the sun) will be viable for billions of years, the conversion process (and viability) is undercut by a number of factors. These include shade, dirt, and panel-to-panel mismatch. In addition, detractors of the technology point to its high cost, but this is a socio-economic factor that won’t be solved by science alone. But scientists at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) have made a huge technological leap.
