Spontaneous generation of interlayers in OPVs with silver cathodes using additives in a P3HT:PCBM layer — Basel Shamieh1, Gitti Frey1, and •Uwe Vogel2 — 1Israel Institut of Technology, Haifa 32000, Israel — 2Helmholtz-Zentrum Berlin für Materialien und Energie GmbH
We report a new efficient methodology for processing interlayers by the spontaneous segregation of an additive to a silver cathode. The driving force for this special migration is the chemical interaction between the thiol end group of the additive HEG-DT and the silver. In addition, we report modification of the silver work function at the interface and effectively increase the device Voc which enhances the device efficiency by 76%.
