Self-healing Solar Cells Mimic Leaves | solar power |

"Solar cells based on organic systems have the potential to become less expensive and more environmentally friendly than silicon-based solar cells, the current industry standard. But the sun’s ultraviolet rays deteriorate  their performance. Now North Carolina State University researchers Orlin Velev and Hyung-Jun Koo have designed solar-cell devices with channels that were inspired by the branching vascular channels that circulate life-sustaining nutrients in leaves and human hands."
