Presentation Transcript

  1. Plasmon enhanced thin-film solar cells: Advanced theoretical analysis and ellipsometric characterization Supervisor: Jesper Jung Postdoc jung@nano.aau.dk Room: 5.140

  2. Introduction • Present day solar cells • Silicon • Abundance in nature • Microelectronic industry • Thick (~250 mm) • Expensive

  3. The idea of the project • Plasmon enhanced solar cells • Thin-film silicon layer (~2mm) • Metal nanoparticels • Localized surface plasmon resonances • Scatter and enhance light strongly at LSP resonances • Analysis using ellipsometry • Theoretical model • Sample fabrication • Measurements

  4. Possible contents • Theoretical work • Modeling of light scattering and absorption of metal nanoparticles in layered geometries • Effective medium theory (Maxwell-Garnett) • Modeling of ellipsometer systems • Experimental work • Fabrication of metal nanoparticles • Fabrication of thin film structures • Measuring using the ellipsometer in the clean room
