At the past two PVSCs, our team presented recent advances in our line-focus space photovoltaic concentrator technology. In the past year, under Phase II and Phase II E SBIR programs and other programs funded by NASA, our team has extended the technology to point-focus concentrators as well, and has made much additional progress in the development of this new family of space photovoltaic concentrators. Both versions use flat, robust Fresnel lenses, high-efficiency 4-junction cells, and innovative graphene radiators. This paper presents the latest advances in this technology. |
