Spacecadet Ventures leads $4 million seed round for spacecraft solar technology startup Arinna

Spacecadet Ventures led a $4 million seed financing for Arinna, a startup developing ultrathin solar cells for spacecraft. The round also included Anorak Ventures and Breakthrough Energy Foundation. Arinna's technology uses transition metal dichalcogenides, a class of atomically thin semiconductor materials, to develop flexible photovoltaic cells designed for the radiation environment of space. The company intends to use the capital to develop qualification panels and prepare its technology for orbital testing. The investment addresses a key infrastructure bottleneck for future spacecraft and space-based computing systems.
