Design of opto-electronic nano-structures, capability for optimization of different solar cells

Development of CAD tools for optical devices is under way to include multi-physics tools. Previously, tools like “RCWA” was used for the diffraction mode of periodic structure analysis, while FDTD is typically used as a general numerical method for analyzing field propagation in the time domain to investigate transmission, reflection, and absorption of electromagnetic energy for devices like optical ring resonators. Meanwhile, for sources it is essential to analyze the semiconductor physics, generation and recombination of electron/hole pairs and the photons generation efficiency linking current to light like in lasers, LEDs, photodiodes, and solar cells.
