Thin, flexible solar shingles have been created by scientists at the National Renewable Energy Laboratory who used Corning's Willow glass. The shingles can be attached to a roof just as traditional asphalt shingles are. The glass-based shingles "could be more durable" than traditional ones, says Dipak Chowdhury, a division vice president at Corning and director of commercial technology for Willow glass. In addition, the use of glass means the solar cell material could be the scalable cadmium telluride.
