Monte-Carlo simulation of an LSC based on stacked layers of fiber arrays with core-coating different absorbing properties

Posted on 09.06.2021 - 19:10
In this work, a Monte Carlo ray-tracing model for the simulation and optimization of a fiber Luminescent Solar Concentrator (LSC) based on stacked layers of fiber arrays is developed and validated. The fiber LSC efficiency improvements are compared against a conventional planar LSC. We developed a new model to analyze the performance of different configurations of bulk-doped fibers and fibers constituted by a doped coating and a passive core. These configurations are analyzed also varying fiber packing geometry diameters, and length. Due to the exceptionally low absorption coefficient of the silica fibers (αwg ~ 10-⁴ cm-¹), concentration factors of up to 1.9 are predicted when dimensions are scaled over 1 m², which improve more than twice the maximum concentration factor ever reported. These results serve as a previous theoretical study for the future development of a new LSC design based on flexible silica micro-fibers coated with Si-QDs doped poly(lauryl methacrylate) (PLMA) layers.
