Solar start-ups set new efficiency records
(PhysOrg.com) -- Although Alta Devices and Semprius make different types of solar panels, both start-ups have been breaking records in the past few days. Santa Clara, Calif.-based Alta Devices announced that its solar panels have achieved an efficiency of 23.5%, which has been verified by the National Renewable Energy Laboratory (NREL) as the highest solar panel efficiency to date. And Semprius, based in Durham, North Carolina, has announced that its concentrated solar panels have achieved an efficiency of 33.9%. Unlike traditional solar panels, concentrated solar panels use lenses to concentrate sunlight at intensities of up to 1,000 suns....
