Plasmon-enhanced ultrathin bulk heterojunction: Interplay between optical and thermal responses of AuNPs

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

The incorporation of metal nano particles affects the efficiency of OPVs in both positive and negative ways. In our previous work, we demonstrated that by appropriately inserting AuNPs in the OPV device, the efficiency can be increased by 30%. In this work we show that AuNPs not only contribute to the increase in the total conversion efficiency of the OPVs by increasing the absorption rate of the active layer, but their plasmonic resonance also changes the characteristics of their surrounding medium. In this work we focus on the electrical properties of PEDOT: PSS and how they change due to AuNPs’ increased E-field and temperature. Further, the incorporation of AuNPs changes the workfunction and thus the exciton dissociation rate of the OPVs.
