Ionically Gated Small-Molecule OPV: Interfacial Doping of Charge Collector and Transport Layer
Ionically Gated Small-Molecule OPV: Interfacial Doping of Charge Collector and Transport Layer
We demonstrate an improvement in the performance of organic photovoltaic (OPV) systems based on small molecules by ionic gating via controlled reversible n-doping of multi-wall carbon nanotubes (MWCNTs) coated on fullerene electron transport layers (ETLs): C60 and C70. Such electric double-layer charging (EDLC) doping, achieved by ionic liquid (IL) charging, …
