January 14, Science Daily: OLED displays, plastics-based solar cells and bioelectronics are just a handful of the many technologies that could benefit from a new discovery by researchers at Chalmers University of Technology (Sweden). Through a process known as “double doping”, the researchers demonstrated that’s it’s possible to move two electrons to every dopant molecule – defying conventional wisdom that these molecules can only exchange one electron each.
In the words of team lead Christian Müller: “We chose to look at a different type of polymer, with lower ionisation energy. We saw that this material allowed the transfer of two electrons to the dopant molecule. It is actually very simple.”
