Analysis of 3-D waveguides in a cylindrical lens solar concentrator

High-efficiency solar cells use waveguides for concentration and higher light harvesting, reducing the area of the solar panels and decreasing their costs. Hence, this work aims to simulate and analyze a solar concentrator built with three cylindrical lenses and three waveguides. The simulation of the model was conducted using COMSOL Multiphysics software. Results show a maximum optical efficiency of 77% and a concentration ratio of 3.5. The lenses and waveguides sets were developed as a single bulk structure. The model exhibits potential for use in photovoltaics and thermal solar conversion with concentrated radiation.
