Read moreEven thinner solar cells through use of nanoparticles?
Researchers have measured how irregularly distributed silver particles influence the absorption of light. They demonstrated that nanoparticles interact with one another via their electromagnetic near-fields, so that local 'hot spots' arise where light is concentrated especially strongly.

Read moreOrganic solar cells more efficient with molecules face-to-face
New research reveals that energy is transferred more efficiently inside of complex, three-dimensional organic solar cells when the donor molecules align face-on, rather than edge-on, relative to the acceptor. This finding may aid in the design and manufacture of more efficient and economically viable organic solar cell technology.
