报告摘要：
Thin film solar cells have attracted much attention because of the potential to provide virtually unlimited clean energy at relatively low cost. Currently, their performances are limited by poor light absorption. In this research, large, broadband, and polarization-insensitive light absorption enhancement was realized via integrating with unique metallic nanostructures. A test shows up to ~30% broadband absorption enhancement when comparing to bare Si thin film solar cells, and up to ~10% improvement at certain wavelengths when compared to bulk Si solar cells. Three possible mechanisms, the Fabry-Perot resonance, surface plasmonic resonance, and planar waveguide coupling, were indentified to be responsible for such an enormous enhancement. Potential integration with other approaches will be discussed as well.
