Design of Plasmonic Nanoparticles for Efficient Subwavelength Light Trapping in Thin-Film Solar Cells

摘要: This paper explores geometry-sensitive scattering from plasmonic nanoparticles deposited on top of a thin-film amorphous silicon solar cell to enhance light trapping in the photo-active layer. Considering as ideal spheroids, broadband optical absorption by layer is analyzed and optimized with respect nanoparticle aspect ratio both cases resonant (silver) nonresonant (aluminum) nanostructures. It demonstrated how coupling sunlight semiconductor can be improved through tuning shape dipolar multi-polar regimes, well discussed native oxide shell formed nanospheroid surface after prolonged action air moisture affects active changes photocurrent generation cell.
