The most efficient solar cells typically have several layers of semiconductor materials, each tuned to convert different colors of light into electricity. Researchers at Lawrence Berkeley National Lab have now made a single semiconductor that performs almost the same job. More importantly, they made the material using a common manufacturing technique, suggesting it could be made relatively inexpensively.
