Abstract
Mie study the stability of a bipolaron as a function of the strength of the Coulomb interaction in conjugated polymers. While strong Coulomb interacti ons will destabilize the bipolaron, we find impurities and image forces ten d to stabilize it, which implies that bipolarons may be important for charg e injection at polymer-metal interfaces in the organic LEDs.
