Scientists at the University of Wyoming are trying to improve solar energy by using nanotechnology.
Researcher Wenyong Wang says nanotechnology involves using very small particles to create solar panels. He says that’s different than how most solar panels are made.
“Commercialized panels are based on silicon,” Wang said. “And right now I think the efficiency is very good – it’s close to 30 percent. … But the disadvantage is that the cost is very high.”
