Extremely power-dense solar for the extremes of space

Arinna, Inc. proposes the development of extremely power-dense transition metal dichalcogenide (TMD) solar cells to meet NASA’s increasing demand for advanced photovoltaic technologies capable of withstanding extreme space environments. These next-generation solar cells offer exceptional power-per-mass, high radiation resistance, flexibility, and self-healing properties, ensuring sustained performance for deep-space missions, small satellites, and lunar exploration. This Phase I effort aims to rigorously evaluate TMD solar cells under critical space-related stressors, including ultraviolet radiation, atomic oxygen exposure, and thermal cycling. In collaboration with D2Solar, we will conduct environmental testing to validate performance and durability. SpaceWorks Enterprises will assist in optimizing the thermal design, structural integration, and power management of TMD solar arrays for a range of spacecraft configurations. Key deliverables include proof-of-concept validation, performance benchmarks, and recommendations for large-scale system integration, paving the way for further technology maturation in Phase II. Beyond NASA applications, TMD solar cells have significant commercialization potential in commercial satellite operations, defense applications, and terrestrial markets, including IoT, automotive, and building-integrated photovoltaics. Their lightweight, flexible, and durable design enables extended mission lifetimes, reduced launch costs, and enhanced spacecraft efficiency, while their scalability positions them as a disruptive solution in the broader solar energy sector. By overcoming the limitations of traditional photovoltaic materials, Arinna’s TMD solar technology represents a transformative advancement in next-generation power solutions, ensuring more resilient, efficient, and adaptable solar energy systems for both space and terrestrial applications.
