Abstract
In this work, we demonstrate silicon thin film with square nanoconical frustum arrays decorated surface via simulation for photovoltaic application. An ultimate efficiency of optimized silicon square nanoconical frustum (SiSNF) arrays based solar cells is up to 31.60%, 3.47% higher than that of silicon thin film based solar cells with silicon hexagonal nanoconical frustum (SiHNF) arrays textured surface, which is close to the perfect Yablonovitch surface. The enhanced ultimate efficiency of SiSNF arrays is insensitive to top diameter and incident light angle. The underlying absorption enhancement mechanism behind the observation is also discussed.
