Absorption enhancement in ultrathin crystalline silicon solar cells with antireflection and light-trapping nanocone gratings.
TL;DR: A double-sided grating design is introduced, where the front and back surfaces of the cell are separately optimized for antireflection and light trapping, respectively, which yields a photocurrent close to the Yablonovitch limit.
