Novel Non-Tracking Fiber Optic Solar Concentrator

Abstract

Inspired by energy requirements for future Artemis missions, the researchers have designed a non-tracking fiber optic solar concentrator based on Fresnel lens capabilities to harness solar energy and convert it into usable power for extraterrestrial applications. Since testing in a lunar environment is not currently feasible, the objective is to implement simulations that will mimic the future Earth- based prototype experimentation to validate software parameters, with the further intent to be adapted to lunar requirements. Design validation, which demonstrated the optical and thermal aspects of each material within the system, utilized mathematical models in conjunction with Simscale, MATLAB, and Optica EM. Researchers used the refractive index and thermal characteristics for each lens material used in the study, finding overall energy efficiency and surface heat intensity for Earth-based simulations. By validating Optica EM and thermal simulations, this scalable and modular Fresnel lens assembly, which requires no ancillary power, can be adapted to fit the needs of extraterrestrial and terrestrial power generation applications.
