Abstract

We report the computational modeling of Ag nanoparticles deposited on the rear of a nanohole-textured silicon thin film to achieve higher absorption for silicon solar cells. The silicon nanoholes and the rear-located Ag nanoparticles can enhance the absorption in the silicon thin film. The short circuit current density for nanohole-textured silicon thin film can be further improved by about 11.6% by Ag nanoparticles. The combination of silicon nanoholes and plasmonic metal nanoparticles provides a promising way to enhance the absorption of silicon thin-film solar cells.
