Electrostatics do the trick
Organic semiconductors allow for flexible displays, solar cells, and other applications. One common problem in these devices, however, is the interface between the metallic contacts and the organic semiconductor material, where undesirable losses occur. Now Dr. Martin Oehzelt has shown what these losses depend upon. His model also explains why a thin, electrically insulating layer between the two materials can facilitate the transition of charge carriers. His results have recently been published in Nature Communications. (2014-06-23)

Light facilitates n-doping of organic semiconductors
Doping organic semiconductors with negative charges is difficult.

These dimers can be introduced into organic semiconductors, but they do not contribute to the conductivity right away. Via short exposure to light the dimers can be broken into individual n-dopant molecules again, increasing the conductivity by a factor of 100,000. (2017-11-23)
