Paper Abstract

A sophisticated light management is important to construct thin film solar cells with optimal efficiency. This is based on suitable nanostructures of different layers and materials with optimized optical properties. To design thin film solar cells with high efficiency, simulation of light-trapping is a very helpful tool. Such a simulation has to take into account the underlying physical properties like plasmonic effects of silver or interferences. To this end, it is important to solve Maxwell's equations on a discretization grid. To obtain an accurate simulation, the roughness of the top transparent conductive oxide (TCO) layer is described by AFM-scan data. To meet the high computational amount in solving Maxwells equations on a finite difference discretization grid, high performance computers (HPC) are used.
