The effect of incorporation of plasmonic
gold (Au) nanoparticle at the interface between transparent
front electrode and hole transporting layer of
molybdenum trioxide is studied using bulk heterojunction
organic photovoltaic cells (OPVs) of poly-3-
hexylthiophene and phenyl-C61-butyric acid methyl ester
(P3HT:PC61BM) fabricated in ambient air condition
as a model system. The current-voltage measurement of
ITO/MoO3/P3HT:PC61BM/Al and Au incorporated OPVs
under AM1.5G light of intensity 1 Sun showed 16% increase
in short circuit current density (JSC) and a 25%
improvement in power conversion efficiency (PCE) with
the incorporation of Au nanoparticles. The external quantum
efficiency (EQE) measurement showed values varying
from 40% to 60% over a wavelength range 350 nm to
700 nm with EQE enhancement over a broad spectral window.
Scanning electron microscope studies were used to
study the morphology of the Au nanoparticles made.
