The Effect of UV-Ozone Treatment on the Performance of Plasmonic Organic Solar Cells.

Unlabelled: Silver nanoparticles (Ag NPs) solution was spin-coated on indium-tin oxide (ITO) glass substrates prior to spin-coating poly(3,4-ethylenedioxythiophene):poly(styrene- sulfonate) (

Pedot: PSS) for the plasmonic solar cells. The sequence of spin-coating of Ag and UV-ozone treatment resulted in different device performance. For devices in which Ag NPs solution was spin-coated on ITO substrates before UV-ozone treatment, power conversion efficiency increased from 3.

Efficient hybrid plasmonic polymer solar cells with Ag nanoparticle decorated TiO2 nanorods embedded in the active layer.

A hybrid plasmonic polymer solar cell, in which plasmonic metallic nanostructures (such as Ag, Au, and Pt nanoparticles) are embedded in the active layer, has been under intense scrutiny recently because it provides a promising new approach to enhance the efficiency of the device. We propose a brand new hybrid plasmonic nanostructure, which combines a plasmonic metallic nanostructure and one-dimensional semiconductor nanocrystals, to enhance the photocurrent of the device through a strong localized electric field and an enhanced charge transport channel. We demonstrate that when Ag nanoparticle decorated TiO2 nanorods were introduced into the active layer of polymer-fullerene based bulk heterojunction solar cells, the photocurrent significantly increased to 14.
