A Material That Could Make Solar Power “Dirt Cheap”
Researchers discover that a material known for a hundred years could lower the cost of solar power.

Researchers developing the technology say that it could lead to solar panels that cost just 10 to 20 cents per watt. Solar panels now typically cost about 75 cents a watt, and the U.S. Department of Energy says 50 cents per watt will allow solar power to compete with fossil fuel.
