ENERGY - PETE Devices Could Harvest Solar's Wasted Heat

Scientists working at the Stanford Institute for Materials and Energy Sciences (SIMES) have improved an innovative solar-energy device to be about 100 times more efficient than its previous design in converting the sun's light and heat into electricity."This is a major step toward making practical devices based on our technique for harnessing both the light and heat energy provided by the sun," said Nicholas Melosh, associate professor of mat ...
