Advanced Development of Space Photovoltaic Concentrators Using Robust Lenses, Multi-Junction Cells, & Graphene Radiators

At the past three PVSCs [1]–[3], our team has presented recent advances in our space photovoltaic concentrator technology. In the past year, under multiple NASA-funded research and technology development programs, our team has made much additional progress in the advanced development of space photovoltaic concentrators. New robust Fresnel lenses, new high-efficiency multi-junction cells, and new graphene radiators have been developed. The paper will present the latest advances in this technology.
