Simulation of Metamaterial Waveguides for Solar Cells Energy by Finite Difference Time Domain Method (FDTD)

Abstract

Solar cells provide a renewable and clean energy by converting the sunlight to electricity. However, it is important to reduce the cost of the solar cell and increase the efficiency in order to be considered as a reliable energy source. In this work, a theoretical analysis for a waveguide structure by using Finite Difference (FD) methods is presented. The fundamental concepts of both Finite Difference Time Domain method (FDTD) and Finite Difference Frequency Domain method (FDFD) are reported in details. Also, a new waveguide solar cell structure containing metamaterial is presented in order to improve the absorption of light. Metamaterial is an artificial material with negative electric permittivity and negative magnetic permeability which is used to absorb a large amount of the incident light. Finite Difference Time Domain Method is used to analyze the proposed waveguide structure. We also used MEEP and MATLAB software to run the simulation of the proposed waveguide structure.
