Dual plasmonic-enhanced bulk-heterojunction solar cell incorporating gold nanoparticles into solution-processed anode buffer layer and active layer

Abstract

A dual plasmonic resonance effect on the performance of poly(3‐hexylthiophene) (P3HT):phenyl C61‐butyricacid methyl ester (PC61BM) based polymer solar cells (PSCs) has been demonstrated by selectively incorporating 25 nm colloidal gold nanoparticles (Au NPs) in a solution‐processed molybdenum oxide (MoO3) anode buffer layer and 5 nm colloidal Au NPs in the active P3HT:PCBM layer. The devices exhibit up to ∼20% improvement in power conversion efficiency which is attributed to the dual effect of localized surface plasmon resonance (LSPR) of Au NPs with enhanced light absorption and exciton generation. Our report shows a guideline on the usage of dual LSPR effect for the solution‐processed polymer solar cells to achieve high efficiencies. (© 2015 WILEY‐VCH Verlag GmbH &Co. KGaA, Weinheim)

Mobility Enhancement of P3HT‐Based OTFTs upon Blending with Au Nanorods

“…Many inorganic nanoparticles and small molecules have been utilized to form composite with P3HT in OTFTs and higher charge carrier mobilities have been obtained successfully . Among these nanocomposite systems, P3HT/Au has been widely explored in numerous electronic devices . Our previous report demonstrated that the threshold voltage ( V th ) of P3HT‐based transistors was controllable regulated by utilizing gold nanoparticles .…”
