Image: Spectrolab Evolutionary, Not Revolutionary Spectrolab , a subsidiary of Boeing, has announced that it is starting mass-production of a very efficient concentrating solar cell, the C3MJ+ (the datasheet above is for the C3MJ, the “plus” version is a newer, slightly more efficient model). With an efficiency at converting sunlight into electricity of 39.2%, this cell would be the most efficient on the market. “Last year we set a new world record for efficiency with a test cell that peaked at 41.6 percent. We now have entered production with ess… Read the full story on TreeHugger
