Comparison of FMM, FEM and FDTD for Absorption Modeling of Nanostructured Solar Cells and Photodetectors

Abstract

We compare FMM, FEM and FDTD for absorption modeling. We discuss optimum choice of modeling method for varying nanostructures, enabling solar cell and photodetector design optimization that would be impossible with a suboptimal method choice. © 2019 The Author(s)
