New technique helps probe performance of organic solar cell materials

Researchers have developed a technique for determining the role that a material's structure has on the efficiency of organic solar cells, which are candidates for low-cost, next generation solar power. The researchers used the technique to determine that materials with a highly organized structure at the nanoscale are not more efficient at creating free electrons than poorly organized structures -- a finding which will guide future research and development efforts.xKzO_G6v-0Y
