This startup says it has found a way to cut the cost of making solar cells in half
Leap Photovoltaic was a finalist in the Cleantech Open competition, which asks companies to use a simple tool to estimate their potential impact on global greenhouse gas emissions. Because the technology could help the solar industry scale up much more quickly, the potential could be huge: The company estimated that it could help save more than 100 gigatons of emissions by the middle of the century.
