Plastic solar-cell efficiency may improve from tech tweak

Researchers at Sweden's Chalmers University of Technology report a development in doping organic semiconductor materials that could improve the energy efficiency of bioelectronics, organic light-emitting diode displays and plastic-based solar cells. The Chalmers scientists worked with an international research team to come up with a double-doping process, getting dopant molecules to extract two electrons within conjugated polymers.
