The impact of this program would be immense to various areas of space exploration and knowledge generation. Our success would be determined by the unequivocal demonstration of the potential for long-lived, high efficiency, flexible perovskite solar arrays. This finding would be a boon for researchers in this area, who have made great strides yet are almost singularly focused on terrestrial power generation. Yet this application indicates the potential for great price reduction, of approximately a factor of 100X reduction in cost per watt. This program has the potential to revolutionize two specific NASA missions: power for CubeSats and surface photovoltaics for Mars through the SAWS program. In the area of CubeSats the standardization of a form factor can have significant impact on cost barriers by leveraging automated assembly and scalable volume economics. As a consequence there is strong interest in democratizing space science missions using a plurality of CubeSats instead of single large satellites. As such a standardized power system compliant with mass scalability is required to carry these CubeSats from research curiosity to full-fledged science mission tools complete with power-hungry technical equipment, communications or electric propulsion. High performance III-V technology is orders of magnitude more expensive and not scalable in manufacture. All of these problems are mitigated by a successful perovskite material. There is a strong desire by private space exploration companies, such as SpaceX, to utilize low cost, typically terrestrial solar cells for space applications. These perovskites may be ideal in suiting their needs, which are largely filled by crystalline silicon. The silicon cells are more expensive, similarly efficient and not radiation hardened. Current perovskite devices reach >20%, but there is potential to reach significantly greater efficiencies, closer to 30% and be competitive with III-V technologies for PV blankets. The blankets may have application in human surface missions as roll-out solar arrays, for, e.g. Martian surface missions. The perovskites absorb light very efficiently and could be useful in low irradiance/low temperature (LILT) missions. The thinness of the material (< 1 micron) not only aids in flexibility but also radiation tolerance and the monolithic fabrication complete with thin metal interconnects provides arcing tolerance to very high voltages. These two properties suggest the perovskite materials may be ideal for direct drive solar electric propulsion.
