摘要

A Fresnel concentrator with fiber-optic bundle based space solar power satellite (SSPS) is proposed as an innovative design in this paper. It consists of a flat Fresnel lens array for solar concentration, fiber bundles to transport the condensed sunlight to the photovoltaic panel and a highly modular sandwich module for power generation/transmission. Operating principle, structure configuration and efficiency of the system are presented in detail. Also, Fresnel concentrator with a secondary homogenizer is designed to obtain high concentration ratio and good irradiance uniformity on the solar cell. Lastly, to maintain the temperature fluctuation within a design requirement, the thermal analysis of the sandwich module is investigated. The obtained results demonstrate the feasibility of the proposed SSPS design.
