By borrowing a trick from optical-fiber technology, a startup makes cells that trap light to create more electricity.
A Santa Barbara, California, company called Solar3D plans to make silicon solar cells that are more efficient than conventional cells by borrowing the light-trapping concept behind optical-fiber technology. The company claims that its three-dimensional design will funnel light into silicon and keep it trapped—giving the material more time to convert it into electricity.
