Absorption Enhancement in Ultrathin Crystalline Silicon Solar Cells with Antireflection and Light-Trapping Nanocone Gratings
Solar cells light trapping antireflection crystalline silicon absorption enhancement nanocone gratings
2012/8/7
Enhancing the light absorption in ultrathin-film silicon solar cells is important for improving efficiency and reducing cost. We introduce a double-sided grating design, where the front and back surfa...
Enhancement of optical absorption in thin-film organic solar cells through the excitation of plasmonic modes in metallic gratings
optical absorption organic solar cells plasmonic modes metallic gratings
