Small bits of metal may play a new role in solar power.
Researchers at Ohio State University are experimenting with polymer semiconductors that absorb the sun's energy and generate electricity. The goal: lighter, cheaper, and more-flexible solar cells.
They have now discovered that adding tiny bits of silver to the plastic boosts the materials' electrical current generation.
Paul Berger, professor of electrical and computer engineering and professor of physics at Ohio State, led the team that reported the results online in the journal Solar Energy Materials and Solar Cells.
Berger and his team measured the amount of light absorbed and ...
