Facile metallization of dielectric coatings for plasmonic solar cells
چکیده انگلیسی

Electroless deposition of Ag nanoparticles on PECVD SiNx:H dielectric layers is a new straightforward chemical bath process well adapted to the realization of plasmonic solar cells. Depending on the stoichiometry, SiNx:H contains a certain number of Si nanoclusters embedded in the silicon nitride matrix, that act as reducing agents for Ag ions in solution and thus allows the deposition of Ag nanoparticles directly on the surface. We investigate the influence of the layer stoichiometry and deposition parameters on the nucleation and growth of Ag nanoparticles, and show how they can be adjusted to control the nanoparticle size and density. We also demonstrate that this facile metallization process can be extended to PECVD SiOx layers, another dielectric coating of interest in photovoltaics.


► Electroless deposition of Ag nanoparticles on SiNx:H layers is studied in detail.
► The method allows a unique control on the nanoparticle size and surface density.
► Surface density varies over 3 orders of magnitude with the SiNx:H stoichiometry.
► Nanoparticle size is adjusted from 10 to >100 nm with the treatment time.
► Electroless metallization method is shown to be applicable to SiOx dielectrics.
