In this work, the formation of gold nanoparticles (Au NPs) was studied. A gold thin film was first deposited by E-beam Evaporation method followed by rapid thermal annealing (RTA) to create nanoparticles with many different sizes and shapes. The localized surface plasmon resonance (LSPR) effect was also determined. By proper engineering of these metallo-dielectric structures, light can be concentrated and “folded” into a thin semiconductor layer, thereby the absorption can be increased. This approach provides a new development for improving light trapping in thin-film solar cells (TFSCs).
