Space PV Concentrators for Outer Planet and Near-Sun Missions, Using Ultra-Light Fresnel Lenses Made with Vanishing Tools

At the past four PVSCs [1-4], our team has presented recent advances in our space photovoltaic concentrator technology. In the past year, under a NASA-funded Small Business Innovation Research (SBIR) program, our team has made additional progress in the development of space photovoltaic concentrators for outer planet and near-sun missions. One noteworthy innovation is in the scalable method of producing the ultra-light Fresnel lenses which provide the optical concentration of sunlight for both point-focus and line-focus concentrators. The new method uses "vanishing" lens molding tools. The paper will present the latest advances in this technology.
