Tiny gold particles boost organic solar cell efficiency: Plasmonic technique helps enhance power conversion by up to 20 percent

Researchers have demonstrated how they inserted a gold nanoparticle layer between two subcells to combine the tandem cell strategy with the plasmonic effect -- a process that concentrates light via scattering from nanoparticles. As a result, a 20 percent improvement of power conversion efficiency has been attained by the light concentration of gold nanoparticles.
