Metal Nanoparticle-Decorated Two-Dimensional Molybdenum Sulfide for Plasmonic-Enhanced Polymer Photovoltaic Devices

Atomically thin two-dimensional (2D) transition metal dichalcogenides have also attracted immense interest because they exhibit appealing electronic, optical and mechanical properties. In this work, we prepared gold nanoparticle-decorated molybdenum sulfide (AuNP@MoS2) through a simple spontaneous redox reaction. Transmission electron microscopy, UV-Vis spectroscopy, and Raman spectroscopy were...

Gold nanoparticle-decorated graphene oxides for plasmonic-enhanced polymer photovoltaic devices.

In this work, gold nanoparticle/graphene oxide (AuNP/GO) nanocomposites are synthesized and used as anodic buffer layers in organic photovoltaic devices (OPVs). The application of thiol-terminated polyethylene glycol as a capping agent prevents the aggregation of AuNPs on the GO surface and further improves the solubility and stability of these nanomaterials in solutions. When AuNP/GO nanomater...

Plasmonic nanoparticle scattering for enhanced performance of photovoltaic and photodetector devices

A variety of approaches are examined for exploiting the optical properties of metal or dielectric nanoparticles, particularly those associated with surface plasmon polariton resonances, to improve the performance of semiconductor photodetectors and photovoltaic devices. Early and recent concepts for employing optical absorption and local electromagnetic field amplitude increases associated with...

Surface Plasmon Enhancement of Organic Photovoltaic Devices

Cu nanoparticles enable plasmonic-improved silicon photovoltaic devices.

This work examines the effect of copper nanoparticles (Cu NPs) on the photocurrent efficiency of silicon photovoltaic (Si PV) devices. An optimized synthesis of stable Cu NPs is reported together with a procedure for their immobilization on the Si PV surface. A comprehensive analysis of the photocurrent and power dependence of the Cu NPs surface coverage and size is presented. A decrease in pho...
