Washington, October. 6 -- In a new study, researchers at Ohio State University have discovered that adding silver nanoparticles to polymer solar cells boosts the materials' electrical current generation.
The study was carried out by Paul Berger, professor of electrical and computer engineering and professor of physics at Ohio State.
Berger and his team measured the amount of light absorbed and the current density - the amount of electrical current generated per square centimeter - generated by an experimental solar cell polymer with and without silver nano-particles.
Without silver, the material generated 6.2 milli-amps per square centimeter. With silver, it generated 7.0 - an increase of ...
