Completed TRL 4 (started at 2, targeting 4)
We propose the development of a “perovskite” solar cell1 capable of a 100X decrease in cost/watt compared to current state of the art (SOA) and specifically designed for in-space manufacture. As part of the output of this program we will specifically target flight opportunities for the technology demonstration and validation. We will develop this next generation space technology utilizing two parallel thrusts: A NASA-led and space-ready vapor deposition thrust and a partner-led inkjet-printed thrust. Each thrust will hold as a goal the development of high efficiency and scalable in-space production of perovskite solar cells and arrays. Meeting this goal would be transformational for future space power needs including: 1) lunar surface power for year-2028 habitats; 2) 100kW-class direct drive SEP tugs; 3) Large solar powered planetary science missions. To qualify these approaches, we will validate the technology development for each thrust according to the standard for space qualification of solar arrays, AIAA-S111 and LEO/GEO arcing standard ISO 11221. All space qualification testing and device design will be led by NASA researchers.
Build up an automated manufacturing system for perovskite solar cells to create very large arrays cheaply and in space.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 4) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
