Science Daily  May 15, 2024 Chemical doping is an important approach to manipulating charge-carrier concentration and transport in organic semiconductors (OSCs) and it ultimately enhances device performance. However, conventional doping strategies often rely on the use of highly reactive dopants which are consumed during the doping process. Achieving efficient doping with weak and/or widely accessible dopants under mild conditions remains a considerable challenge. An international team of researchers (Sweden, Italy, South Korea, UK, Italy, USA – Georgia Institute of Technology) showed that a previously undescribed concept for the photocatalytic doping of OSCs that used air as a weak oxidant (p-dopant) […]
