This paper describes a cooperative quantum dot and plasmonic effect on improving the performance of dye synthesized solar cells in which CdS QDs, gold nanoparticles (GNPs), and gold nanorods (GNRs) are incorporated into the active layer. Cooperative nanoparticles show superior behavior on enhancing light absorption in comparison with single nanoparticles, which led to dye synthesized solar cells with a power conversion efficiency accounting for a 147% enhancement. The cooperative CdS QDs and plasmonic effect aroused from cooperation of resonance enhancement of QDs and two different nanostructures. Detailed studies shed light into the influence of quantum dots and plasmonic nanostructures on dissociation, exciton generation, and charge transport as well as recombination inside these devices.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
