The Tiny Solar Cell That Could Make a Big Difference in Sustainable Energy As we hurl past the darkest period of the year, let's hear it for some bright news on the sustainable energy front. The U.S. Department of Energy's National Renewable Energy Laboratory recently validated greater than 41 percent efficiency at a concentration of 1,000 suns for tiny cells made by Semprius , a company that is developing low cost, high performance concentrator photovoltaic (CPV) modules to make solar power generation economically viable. This is one of the highest efficiencies recorded at this concentration. The energy conversion efficiency of a solar cell is the percentage of sunlight converted by the cell into electricity and the Holy Grail of the solar industry. Currently the standard conversion rates vary between 10 and 15 per cent. This low-cost approach, which Semprius executives s...
