Regulating electron "˜spin' may be key to making organic solar cells competitive
Organic solar cells that convert light to electricity using carbon-based molecules have shown promise as a versatile energy source but have not been able to match the efficiency of their silicon-based counterparts.
Now, researchers have discovered a synthetic, high-performance polymer that behaves differently from other tested materials and could make inexpensive, highly efficient organic solar panels a reality.

The polymer, created at the University of Washington and tested at the University of Cambridge in England, appears to improve efficiency by wringing electrical current from pathways that, in other materials, cause a loss of electrical charge. Read More
