Space Photovoltaic Research and Technology (SPRAT) Conference

The 29th Space Photovoltaic Research and Technology (SPRAT) Conference, hosted by NASA's Glenn Research Center, will be held onsite at NASA GRC on August 18-20, 2026, in Cleveland, Ohio. At this conference, researchers and users discuss current trends, issues, and mission applications in the development and use of photovoltaic (PV) systems for space. This meeting is fully in-person and will not include a hybrid option. Topics of interest for this year's SPRAT include but are not limited to: III-V and silicon PV technologies, Thin film and alternative PV technologies (perovskites, CdTe, CIGS, etc), Tandem and multijunction research efforts, Interconnect, coverglass, module, and blanket technologies, Space array designs (including in-space, surface, and concentrators), Photovoltaic power system designs (including PMAD, power modelling), PV testing, characterization, and qualification, PV manufacturing and process improvements to reduce cost, Environmental interactions, Missions and flight experiments, Photovoltaics for laser power beaming.
