Researchers at Ohio State University are experimenting with polymer semiconductors that absorb the sun's energy and generate electricity, reports Science Daily. The goal: lighter, cheaper, and more-flexible solar cells.
Researchers have discovered that adding tiny bits of silver to the plastic boosts the materials' electrical current generation. Without silver, the material generated 6.2 milli-amps per square centimeter. With silver, it generated 7.0 -- an increase of almost 12 percent.
