David Ginger, Professor and Raymon E. and Rosellen M. Lawton Distinguished Scholar in Chemistry, and Alex Jen, Boeing/Johnson Chair Professor of Materials Science & Engineering, along with other researchers, have recently reported on the role of electron spin in creating efficient organic solar cells. Their findings were recently published in the journal Nature.
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. These 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.
