3D-FDTD Analysis of Absorption Enhancement in Nanostructured Thin Film Solar Cells

Abstract

We investigate 1D-2D photonic crystals for light absorption enhancement on thin film photovoltaics (Si, GaAs an InP) by FDTD. A comparison with RCWA and TMM is presented. The absorption is increased substantially for these systems. OCIS codes: (160.5298) Photonic crystal; (310.6845) Thin film devices and applications; (040.5350) Photovoltaic.
