Creation of Au nanoparticles decorated MoO3 nanorods using CoSP and the application as hole transport layer (HTL) in plasmonic-enhanced organic photovoltaic devices
Surfactant free MoO3 nanorods (50 nm-5 tun long and 50-300 nm diameter) with Au nanoparticles with varying nanorod dimensions and Au fraction have been synthesized in-situ by using inexpensive continuous spray pyrolysis (CoSP) technique. In-situ grown gold nanoparticles (similar to 10-20 nm) with MoO3 nanorods (Au/MoO3) were obtained which proved useful in getting the additional effect due to plasmonics. The CoSP-synthesized Au/MoO3 nanorods have been used as anode buffer layers in organic photovoltaic devices (OPVs). The resulting devices exhibit a remarkable enhancement in power conversion efficiency (from 2.22% to 3.71%) when Au/MoO3 nanorods were used in the device which can be attributed to the strong localized surface plasmon resonance (LSPR) absorption.
