Abstract

Size-tunable Ag nanoantennas for integrated metasurfaces (MTS) achieved by nanosphere lithography enable new photon management possibilities, facilitating a relaxation of the fundamental Snell’s law for light refraction. Thus, the refractive index for accumulation layer (ITO) of solar cell can be dynamic controlled by voltage on ITO/SiO₂ junction to focus and trap sunlight in the active area of the tandem cell. The OptiFDTD software allows us to design, analyze and test this modern photonic device with arbitrary model geometries and places no restriction on the material properties of the tandem cells for wave propagation, scattering, reflection, diffraction, polarization and nonlinear phenomena.
