Astro Voltaics manufactures ultralight, high‑specific‑power solar cells that achieve 3000‑4000 W/kg and over 32% AM0 efficiency using a proprietary multi‑junction stack. The panels are radiation‑hard, flexible or rigid, and priced below $25 per watt, enabling satellite makers and deep‑space mission providers to reduce mass and increase power for longer missions.

Problem
Spacecraft power systems are constrained by the mass and efficiency of solar arrays, limiting payload capacity and mission duration, especially for large constellations and deep‑space probes.
Solution
Astro Voltaics produces ultralight, high‑specific‑power solar cells that deliver 3000‑4000 W per kilogram with over 32% efficiency. The cells use a proprietary multi‑junction stack combining silicon, III‑V materials, and advanced anti‑reflection coatings to capture a broad solar spectrum while remaining radiation‑hard and flexible. Designed for both low‑Earth‑orbit constellations and decades‑long deep‑space missions, the technology targets a cost below $25 per watt and a five‑year operational life, enabling lighter, cheaper, and more powerful orbital power solutions.
Target Audience
Primary customers are satellite manufacturers, constellation operators, and deep‑space mission providers seeking high‑performance, low‑mass solar power solutions for spacecraft.
