Whitepaper #372 in the Decadal Survey for Solar and Space Physics (Heliophysics) 2024-2033. Main topics: basic research. Additional topics: other basic research; space-based missions/projects; user-need-driven basic space weather research.
Combining thin film solar array technology and solar sail technology will result in a large area thin film solar array that can achieve more than 300W/kg from a vehicle platform as small as a CubeSat. Investing in research and development projects that will close the technology gaps identified in this paper will enable future heliophysics missions to meet any high-power requirements.
