Admit it. You fried an ant under a magnifying glass. It’s OK. We did it too. Now scientists are reporting a breakthrough in a similar technology that could bring down the cost of solar power.

About 50 percent of the cost of solar power is due to the materials and manufacturing of solar cells, essentially pieces of silicon that convert sunlight into electricity. By concentrating the sunlight, you can get the same amount of power with fewer cells.
