Organic solar cells more efficient with molecules face-to-face

Mon, 04/07/2014 - 9:14am
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.

New findings to help extend high efficiency solar cells' lifetime

Mon, 04/07/2014 - 8:05am
Scientists have made a surprising discovery about the degradation of solar cells that could help pave the way to creating a longer lifetime for these cells.  Key factors for creating cost-efficient solar cells to compete with conventional energy sources like fossil fuels include fabrication cost, efficiency and lifetime of the cells.
