Arinna raises $4M seed round to solve the space power problem

In a significant move to address the energy demands of space exploration, the startup Arinna has successfully raised $4 million in seed funding. Founded by Stanford PhDs Koosha Nazif and Alex Shearer, the company is developing ultrathin solar panels made from an innovative material that emerged from their doctoral studies. The funding round was spearheaded by SpaceCadet Ventures, with contributions from Anorak Capital and the Breakthrough Energy Foundation. While the company opted not to disclose its valuation, it aims to have its first solar products tested in orbit by year-end. After validating their technology in space, Arinna plans to establish a facility capable of mass-producing these advanced solar panels by 2028. "We are creating qualification panels for our initial customers to prove that our two-dimensional photovoltaics can withstand the rigors of space while maintaining efficiency and durability," Shearer stated. As they work toward this goal, the team is perfecting the processes required to manufacture their solar cells efficiently. Arinna’s focus is on crafting solar panels specifically tailored for spacecraft. Historically, most satellites relied on expensive and robust solar panels made from rare earth elements. However, with the rise of mass-produced satellites, there's a shift towards cheaper silicon panels, which unfortunately degrade faster due to cosmic radiation. Arinna addresses this challenge with its unique technology based on transition metal dichalcogenides (TMDs)—atomically thin semiconductors that have only recently been developed. The ultrathin solar cells promise not only flexibility but also cost-effectiveness and durability compared to traditional space solar panels. Ben Gaddy, a materials scientist from Breakthrough Energy, commented on the innovation, stating, "While many solar advancements focus on minor improvements to existing technologies, Arinna is leveraging a completely different class of materials." Nazif and Shearer’s collaboration began at Stanford, where Nazif focused on materials for photovoltaic cells while Shearer explored scalable production techniques. Shearer humorously noted their partnership: "Koosha was very much the architect, and I am construction." Arinna's solar technology is projected to be 32% more efficient than conventional panels, with a lifespan of 15 years in orbit and rapid delivery times. These advancements could mark a significant leap forward for space technology, provided the company successfully navigates its upcoming orbit tests and scales up production. Wiz Khuzai, a partner at SpaceCadet Ventures, expressed optimism about Arinna's potential impact, stating, "Power is often a bottleneck for space operations, and Arinna is poised to unlock the next generation of power solutions for space."
